Description Jiri Mzourek 2001-11-26 15:45:21 UTC 
How to reproduce:
1) Run IDE in MDI mode (I've tried it with new userdir)
2) Dock "properties" bottom of "explorer"
3) Attach "source editor" top
4) Attach "output window" bottom

Start to "play" (change windows size, move, etc.). After a while, MDI will be 
unusable in all worspaces. See attachment -- it's better than word description.
I've tried it on JDK1.4rc and W2k and in NBbeta4 and in latest build too.

Comment 9 Jan Zajicek 2001-11-29 09:46:12 UTC 
The patch seems to solve the problem. Tested on build #200111280300.
Comment 10 mslama 2001-11-29 10:27:08 UTC 
I found the root cause if weird: Call of Rectangle.setSize() does not
work correctly in all cases in PerimeterLayout.flip(). Workaround is
to rearrange code. Now I store values in local variables before call
of setSize() but I found that also other changes eliminate this behaviour.

Described broken MDI is result of this incorrect behaviour.

I also filed bug #4532741 to JDK 1.4.0-b87 to Bugtraq.

Fixed in release33 branch.
Comment 11 Jan Zajicek 2001-11-29 10:32:22 UTC 
Vote for putting this into 3.3.0 too.
Comment 12 mslama 2001-12-03 12:48:31 UTC 
Fix is merged to release330 branch.
Comment 13 Jan Zajicek 2001-12-04 11:25:59 UTC 
verified in both release33 and release330 builds
Comment 14 Jan Zajicek 2001-12-04 13:31:40 UTC

Comment 15 Quality Engineering 2003-07-01 16:42:58 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
