There have been several examples in the past. Search the mailing
list for them and use the old tarball they appeared in. Please
don't waste my time generating artificial buggy situations for
you.

It can't.

I don't. Sometimes it's better to live without certain "features"
for the sake of code maintenance.

It's a gkrellm problem. Period. Not every bug in applications
can be circumvented by the window manager.

easy to understand.
