Sorry, i didn't get what do you think should be updated in the current
fix? This is a regression fix. I just reverted part of the previous
patch to fix the problem. And in all places I changed the whole desktop
size should be used, not a primary monitor screen size. And
Toolkit.getScreenSize() has been always returning the whole desktop.
If you think that Toolkit.getScreenSize() should be changed to return
the monitor-1 size, I don't mind to file a separate bug. I'm sure it
will require to revise a lot of usages of the method including those
you've mentioned. Probably, it will cause compatibility issues and will
not be approved then. So, how is that related to the current fix?
