Thanks very much for the link.  That bug report and related ones makes 
interesting reading: I can see now that Swing/AWT problems are probably behind 
a few problem reports of this kind we've had.

I tried out the test case in that particular bug, and it does seem to be fixed 
in the JRE is claims to be fixed in.  But looking at the horror-show that is [1], I can believe there are other problems, and the behaviour will 
be different with different JRE versions.

There's certainly scope for adding fixes/workarounds to the multiwindow mode 
internal window manager so that AWT does the correct thing, but I guess what I 
need to progress this is a test case I can easily run, and 'java -version' for 
the platform the test case should be run on
