1) Copy/paste problem .
Looks like Maple is not able to copy/paste the output
from a summation command . Look at my example .
I have to use the " lprint " command .
2) Mysterious small box character .
Suppose I want to edit a command . I want to replace a character with a left bracket
(or right bracket or left accolade but strangely not the right accolade).
I put the cursor on the character and type the left bracket (or right...) .
The left bracket ( or right ...) is inserted . Now when I try to delete the character,
a small box appear . The character I am trying to delete is shifting to the right .
Like I said , just a little annoying .
3) Open file problem .
The first file I open in Maple with the ctrl-o command , the "open file window" appears in
the center of the screen . All the others files I am opening , the "open file window" show up
in the bottom left corner , top center or top right corner ... randomly .
Very annoying on a 27" screen . For this last one ,I am not shure if it is a Maple 2018 problem
or a Windows 10 64 bits problem . I have few programs in my computer .
When I use Microsoft Paint or Wordpad ,I don't see this problem .
I don't know if somebody else can confirm those annoying things . If I am not the only one
then I am hoping the next updates or versions will fix that .
