Hi Michael,

The cursor that's displayed when an application is busy is controlled by the operating system.  For example, on Windows 7 you can change the busy cursor by going to "Control Panel - Mouse - Pointers".  The default busy cursor is an animated circle that looks like:

  

Could you describe exactly what you're seeing when Maple is running a long calculation?  Note that you'll only see the busy cursor when you hover over the document or worksheet area of Maple.  If you move to the Maple menu bar or palettes you will see a pointer with an hour glass.  If you move the mouse off of Maple completely the cursor will return to the regular pointer.  The behavior should be the same in Maple 15 as it was with previous versions.

Hi Isaac,

If you could show us your work we should be able to see where you're going wrong.  I get the same result in both Maple 13 and 14:

restart;

with(DifferentialGeometry):

with(DifferentialGeometry[Tensor]):

Preferences("ShowFramePrompt", false):

DGsetup([z, w, u], Lob):

g:=evalDG(dz &t dz + cosh(z/a)^2*dw &t dw + (cosh(z/a)^2*cosh(w/a)^2)*du &t du);


RicciScalar(g);


 

For more information on Tensor Calculus using the Differential Geometry Package, you may refer to this article on the Maplesoft Application Centre:

The DynamicSystems package was added in Maple 12, so it won't be available in versions of Maple 11 and earlier.

This is actually a known issue with older versions of Java (like the one Maple 10 uses).  You can find the solution here:

Basically you'll just need to add a line like "maxheap=700m" to Maple's launch.ini file.

Alex, I assure you that our Technical Support does not "ignore" request from our users.  In fact, you've taken it upon yourself to post our email responses to you on this forum several times.  So we're definitely not ignoring you.

As I've mentioned to you before, perhaps your email is misconfigured. It looks you've had trouble in the past receiving emails from both Technical Support and the Maple T.A. hotfix mailing list .  It might be more productive for you to contact me directly rather than relying on your MaplePrimes postings to launch complaints.  I can work with your network administrator to make sure your email is configured properly and that no messages from us get blocked.  If you'd like to contact me directly my maplesoft.com email address is blaarakkers.  I look forward to hearing from you.

It's possible to connect to a MapleNet server from a Macintosh machine, but we do not currently have a version of MapleNet that installs on a Macintosh server. I don't think that this has been requested before, so I have added this as an SCR feature request.

Hi Alex,

did you apply the hotfix mentioned in the email from Technical Support?  Hotfix 500-005 was created to address this issue and can be found on the Maple T.A. 5.0 Hotfixes webpage:

http://www.maplesoft.com/support/downloads/mta_hotfixes50.aspx

Applying the hotfix will not undo the damage done, but any course module imported subsequently will retain the question bank/topic/question structure. 

Note that Maple T.A. Hotfixes must be applied sequentially, so you must install hotfixes 500-001 to 500-004 before applying this one.  This hotfix is also included in the Maple T.A. 5.01 installer, so users upgrading from Maple T.A. 4 with this installer will find the question/topic structure preserved (implemented as question groups/subgroups).

If you missed the hotfixes when they were posted on the website then I would recommend signing up for the Maple T.A. Product Hotfixes mailing list:   

http://www.maplesoft.com/subscribers/subscription_list.aspx

That way you'll be notified by email whenever a new Maple T.A. hotfix is released.  I hope this helps.

There are also some nice examples in the Maplesoft Application Center:

It might be best to contact support with the details of your problem.

The security warning is nothing to be concerned with (it's actually warning as opposed to an error).  This is just telling the user that the digital signature is trusted but it has expired.  However the behaviour that Robert is seeing is very strange.

The jar files needed to run the math oracles are quite large and could take a minute to download and cache in the client's Java Cache (not the browser cache).  So the applets used in these worksheets won't be responsive until Java has finished downloading all the jar files.  It's also possible that 1 or more of these jar files on the computer are incomplete or otherwise corrupt.

I do have a few suggestions:

• clear the browser cache (in Firefox go to "Tools - Clear Private Data", select all the check boxes and click "Clear Private Data Now")
• clear the Java cache (in Windows go to the Control Panel - Java, click the Settings button below Temporary Internet Files, then click Delete Files)
• Test your Java installation (http://www.java.com/en/download/help/testvm.xml)
• Make sure Java is up to date (http://www.java.com/en/download/index.jsp)

If you're still having problems let us know!
