Due partly to this and partly to Bug #112107, I had to abandon Compiz and revert to plain 2D Metacity. I have not yet upgraded my main PC to Gutsy, so I've not tried it in 7.10 yet. My testbed PC is too old to support Compiz and I have had to remove Ubuntu from my notebook due to multiple hardware incompatibilities in the kernel. So I can't yet verify if this problem is fixed in 7.10. I will report back when I have tried it.
