#1046 after alt-tab, ceases passing input to applications

[Anonymous]

Fluxbox 1.3.1 (packaged version, Ubuntu 11.10)
xorg-server 1.10.4

Sometimes after alt-tab, I see the following behaviours:
* keyboard and mouse input no longer passed to applications
* unable to change window focus with mouse (alt-tab will)

I haven't been able to determine particular circumstances which trigger this. Restarting fluxbox will usually make the symptoms go away, but the next alt-tab will often trigger the bug again.

Sounds like the input or server being grabbed by fluxbox, but isn't reproducible here.
Can you still cause this?
