@acer I asked here first to see if I was the only person experiencing this problem. Thanks. 

@acer Sorry, I mistyped! I meant to have written that the GUI's Options setting,
   "Open worksheets in" -> Tab
corresponded to the preferences file item,
   MDIOnOpenAndNew=true
-------------------------------

SG> No worries. I truly appreciate your effort to solve this odd problem. As we both know, if one possesses this problem, others would like to do it as well.
-------------------------------

So, what happens if you File->Open multiple files from within the GUI, as opposed to from the desktop launcher? Does it open them all in tabs, or in separate windows?
-----------------------
SG> Yes, in tabs if launched within the program.
---------------------

Can you open the very same .mw file more than once, concurrently, using the desktop launcher?
-------------------------
SG> If the file is open, then double-clicking on the file in the file-manager brings me back to the originally opened file. 
---------------------

If you open the desktop launcher icon's Properties and examine its call to Maple (text code), does it pass any opens to the Maple executable?
--------------
SG>Your question is above my pay grade. I can find maplew.exe. I can select it's properties. At this point, I have no idea how to proceed. 
----------------

ps. Have you tried the (legacy) accesibility GUI in your M2025? (Basically, the old Java GUI, IINM.) I'm not suggesting that you switch; I'm just interested in whether the problem is there too.
----------------------
SG> Help me on how to proceed to answer this question.
--------------------

pps. I like to think that here we all have far more in common than we have differences.
----------------
SG> and they said Mulroney was dangerous. 

@acer 

In the menu, the option of how to open is definitely set to TAB. However, in the Maple.ini in the hidden folder of "c:/users/All Bow to the Maple Lord/AppData/Roaming/Maple/2025", the option MDIOnOpenAndNew is TRUE. 

Changing the line MDIOnOpenAndNew = false, when opening Maple, the menu option changed from TAB to WINDOW. Is this not the opposite of what you wrote? Regardless, the undesired and novel behavior persisted. 

I installed both without importing the preferences of 2024 and importing them. (2 different machines) I will be updating a 3rd device from my beta install now that the good folks of Maplesoft heeded my desperate pleas to modify the 2d input editing "feature." We will see what happens. However, I suspect it is a conspiracy to cause the American educational system to improve its efficiency by causing it to constantly restart new sessions of Maple. 

(Yes, this post is dripping with both irony and sarcasm. Forgive me. I did everything (legally) I could to rid the world of the ^%$#ing insane "leader" of the country in which I live.)

@C_R Well, the joke is on me. I was using a previous build. I finally got a copy of the most up-to-date version. And lo and behold! The behaviour that I was seeing in beta, and strongly advocated to be changed, was changed. Good on them! 

So, sorry to cause the confusion of this discussion. 

@C_R I have never used Linux. Isn't the Linux interface the same as that of Windows?

I'm not sure what you are trying to do. No file was linked in your reply. Here is what I am referring to. 

Download Enhancement_to_input_problems_and_solutions.mw

@C_R Sorry, but that is the enhancement that they are promoting with 2025. I spoke against it, using numerous examples. Others did as well. But they chose to keep it because they felt the number of times one write 1/N+1 with N+1 in the denominator was small compared to the number of times one writes 1/N. 

I have created a video reviewing the key UI changes and the enhanced editing. It answers most of the questions people asked about it when they switched to 2025. The questions that @nm asked.

https://youtu.be/5jT8o5g0zcg

 At the end of the video is how to avoid the pitfalls of the enhancement. 

To write the example I gave, put a space between the N and +, or put a space before you write N. 

1/N<space>+1

or

1/<space>N+1

But the worst is the numerator / function(, such as g(x)/f(x).

@C_R Maplesoft allowed me to share with the students version 2025 in class during the beta cycle so that they could receive feedback. There is no doubt that many are ready to move to the more modern interface. 

Of course there are some bugs that need to be fixed. However, unlike 2024, which I found so buggy during the beta that I didn't use version 2024 until 2024.2, I quickly switched to 2025. I've been very happy with the interface and the 2d input, with the exception of 2d input enhancement.  There is a huge problem if one writes stuff like g(x)/f(x) or even just x / f(x). 

@C_R What you describe is something that I have faced several times while teaching class. So, sad face. 

The best I can tell you is that the Maplesoft folks should be aware of the lack of Windows operations. Previous editions worked. So, I expect several improvements by 2025.1.

@C_R Click on the title bar. Drag it to the left or right enough so that you can see the left or right edge of the window. Then, drag the edge toward the center. You may have to repeat this process several times. 

@awass Forget whatever you wrote. There may be an unprintable character in there. 

Otherwise, I could copy and paste your code into another section.

@awass to upload your worksheet, use the big green up arrow on the webpage.

I don't understand what you are trying to do and why it fails.  Maples interface isn't much different than Microsoft office apps.

@awass what version of Maple are you using?

@awass You didn't upload a worksheet. Nor do you say which version you are using. But it works for me. Did you remember to use <shift><enter> to enter the subsequent lines in the execution group?

@Carl Love To match Microsoft Office apps, Options/Settings is under the Files tab. However, it is on the left side of the vertical bar, where one's eye is more likely to catch it. 

Fun fact: The height of the ribbon in Maple 2025 is exactly the same as the ribbon in an Office program.
