I use OpenBSD 4.2. The application
/usr/local/jdk-1.7.0/bin/java -jar cgoban.jar
# from http://files.gokgs.com/javaBin/cgoban.jar
runs properly with fvwm, but not so with cwm.
The first window has an extra grey border on the bottom and right
[ http://i.imgur.com/5c1I2.jpg ]. I click the "Play on KGS" button.
When I resize that window, its contents don't shrink and expand
properly, but I get clipping [ http://i.imgur.com/a3Ykt.jpg ] and an
extra grey border [ http://i.imgur.com/B2F00.png ]. Also, it becomes
impossible to enter something in the "Name:" and "Password:" lines.
There is more breakage after connecting to the KGS server.
I updated just /usr/xenocara/app/cwm from -current cvs and installed
it. The symptoms persist.
