2008 Cmd Mgr Issue

I tried giving command manager a try..
So, i have been using it for almost 2 days.
I wish i could move it.. Still don't like it... But that's anotherissue..

Anyway, I set it up how i could use it.. Added & removedbuttons, etc..
Then i start getting "Failed to Save" errors...

So, I notice a pattern..
Whenever i modify the command manager. Add custom Tabs.. ChangeButtons around.. I get periodic "Failed to Save" error's followedby crashing..
Upon restarting SW, the CMD Mgr is back to default also..

Only does this when i modify the Cmd Mgr...
If i leave it alone, i don't get the failed to save..

Pretty wierd, Has anyone else experienced this?SolidworksUser Interface
