In a recent MaplePrimes question: https://mapleprimes.com/questions/240543-Maple-20251-On-Windows-11-How-To-Resize 

a discussion of interrupting a computation also came up.

I gave some comments. In one of these I wanted to include a link to a screenshot. 
I tried several times. It seemed that I only had the choice between the full image or a thumb nail.
So I chose the latter. That appeared to me as worthless. I tried a couple of times more, but decided to delete all 3.

Then I wrote a comment without a screenshot. 

It looks silly to have these empty (and anonymous) "comments" still around.
Is there any way to remove these?

Consider the following simple procedure:
 

restart;
p:=proc(x::{realcons,{set,list}(realcons)} ) x end proc;
p(8);
p({8,9});
p([7,8]);

I would like to be able to do something like this instead:

q:=proc(x::{ID,set,list}(realcons) ) x end proc;
## ID(realcons) should just be realcons.
q(8); ## Obviously we get an error.
q({8,9}); #OK
q([7,8]); #OK

In Q below ID is simply s->s, but that won't work in q.
Q works because the type check evaluates its arguments first.
 

Q:=proc(x) 
    if type(x,{s->s,list,set}(realcons)) then 
      x 
    else 
      error "%1 expects its first argument to be of type %2", procname,{s->s,list,set}(realcons)
    end if
end proc;
Q(8);
Q({8,9});
Q([7,8]);

I believe that Carl Love had a solution on MaplePrimes some years ago, but I can't find it.

In Maple 2023 I haven't been able to sign in to the Maple Cloud.
In Maple 2022 there was no problem. In fact in my Maple 2022.2 I'm actually signed in right now.

I need this to get updates to the Physics updates. 
The toolbar in 2023.2 has a grayed out icon saying "Sign in". Nothing happens if I click on it.

PS. I'm also signed in right now to Maple 2021.2. So the problem couldn't be that I cannot be logged in to more than one Maple release.

In a do loop with a try... catch statement I had placed an assignment to a vector element after catch: but before the line printing the lastexception. That the loop didn't perform as expected, but resulted in an error about ListTools:-FormatMessage wanting its first argument to be a string surprised me. Putting the assigment to the vector after the exception printing worked fine.
It seems that rtables are the exception (no pun intended) to the order being irrelevant.
 

restart;
V:=Vector():
for j from 1 to 5 do
  try
   V(j):=j/(j-1)
  catch:
   V(j):=17; # clears lastexception apparently
   printf(cat(StringTools:-FormatMessage(lastexception[ 2 .. -1 ] ),"\n"));
  end try
end do:
#####
restart;
V:=Vector():
for j from 1 to 5 do
  try
   V(j):=j/(j-1)
  catch:
   printf(cat(StringTools:-FormatMessage(lastexception[ 2 .. -1 ] ),"\n"));
   V(j):=17;
  end try
end do:

These simple lines confirm my observation:

restart;
lastexception;
5/0;
lastexception;
5/5;
lastexception;
x:=47;
lastexception;
table();
lastexception;
[1,2,3];
lastexception;
rtable();
lastexception; # Now cleared!
