There's a bug reported against Java relating to this, with some more
details. It claims to be fixed, but it still occurs. There's a small
test case in the bug report. It makes many Java UI applications
unusable with Cygwin/X.

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
XWM.java [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
