Applcation not responding- cannot end

With Defense+ active, I cannot end an application which is not responding. Checking Task Manager reveals dumprep.exe is hanging. The Defense+ log shows:

25 August 2007 12:13:05 C:\WINDOWS\system32\csrss.exe Terminate Process C:\Program Files\Comodo\Firewall\cfp.exe 25 August 2007 12:13:44 C:\WINDOWS\system32\csrss.exe Terminate Process C:\Program Files\Comodo\Firewall\cfp.exe

The problem seems to arise when trying to switch between applications while Defense+ has a pop up showing.

Today I was switching between a printer window and a browser window and noticed a Defense+ pop-up. Then everything locked up. Killing dumprep.exe let the application end, but a reboot was required to get back to normal. (Actually I had to kill quite a few dumprep.exe’s- one for each time I’d clicked ‘end now’.)

Last night I experinced the same problem using FastStone Capture while a pop-up was showing.
