--- Comment #52 from Andrew Gaydenko a@gaydenko.com 2010-05-10 04:16:47 --- Heh.. Ok, I'll try to describe the issue again :-)
Say, we have internal window inside main window, and the first one doesn't touch any edge of the second. Now, let's try to resize intenal window this way: take with mouse, say, right bottom corner and drag it towards right bottom corner of the main window. At the moment when you drop "resize mouse pointer" - and last one touches any edge or right-bottom corner of main window, scroll bar(s) suddenly appears. Expected (and old, very old :-)) behavior: after dropping resize pointer, intenal window is resized to be *adjoining* internal window edges. *Without* any scrollbars.
