property page not opening

For some odd reason, device manager property page is not opening when I
select 'Resources'. It happened few times on USB driver and I also
observed firewire host controller driver. Both the drivers are inbox
drivers. If I reboot the PC, I can get device manager normal back
again.

Any hint why device manager 'resources' tab locks up. When PC is in
this state, connecting a USB on any port is not recognised. Same with
firewire.

Thanks,

Finally I solved the mystery. There is problem in my device driver. I
was acquiring 'remove lock' and not releasing in one path of execution.
That somehow caused the problem that locked 'resources' tab of totally
unrelated driver in device manager. May be because the lock is global.
