Webuilder 10.02.118 not closing

[WDB]

Hi, I've just upgraded from WeBuilder 10.00 to the latest 10.02.118 version and ran into the problem that WeBuilder refuses to close by clicking the normal upper-right red X button. The only way I can close WeBuilder 10.02 is through the Windows Taskmanager.
I did'nt have this problem with WeBuilder 10.00.
This only happens after doing some Previews
My OS is Windows XP sp3.

This happens to me very infrequently, so much so that I have not yet found any way of replicating it with regularity. I wait a few minutes and close it fine when whatever is locking it 'lets go'. I might download Unlocker and the next time it happens, try to unlock webuild.exe and see what, if anything, is holding onto it and preventing it closing.
