Unknown program waiting to shut down

[BenTrein]

On Kernel 2.6.31.12-174.2.3.fc12.i686.PAE, whenever shutting down I get the attached error message. What the H is that? The computer waits for an UNKNOWN program to shut down? Did I just boot Windows looking like Fedora???

Only you have the logs on your system. Check out /var/log/messages and/or maybe dmesg and see if anything looks interesting during shutdown.

That's interesting,in place of unknown there's Firefox in my case.Running F11 kernel 2.6.30.10-105.2.23.fc11.x86_64 ,FF3.5.9.
What helps is to open system monitor>processes>shut ff manually.
