Freeze at shutdown/restart

Freeze at shutdown

My songbird works like a charm besides a few bugs. I can only give praise to our helping community so far.

Ive got a problem at shutdown.

When i shut down the app by clicking the exit icon, songbird freezes for about a minute.
After the freeze it shuts down on its own but i dont know if its shutting down correctly.
The same thing happens when i click the restart buttun after installing an add-on.
Songbird freezes fr a minute or 2 and then it shuts down on its one. And most of the time actually restarts itsself, but even that not always happens.

Has somebody got any ideas on what could cause the problem.
