Has someone else experienced something like this with Delphi and if so is there a known workaround!
I’m using the Delphi 2010 Rad Studio on Windows 7 64 bit.
A few times when editing the IDE hangs and I can’t do any action either by keyboard or mouse. But there is a error-beep sound from windows like there is a modal window open somewhere, but hidden behind the ide it self.
Only by ending the ide via Task manager can I make this hidden modal window visible.

I have the same problem with older versions of Delphi like D6.
My solution is use another tool like WinExp –Windows Explorer– or WinResQ to explore the existing active windows on system and reactivate it (BringToTop).
With this solution I get the Delphi IDE on Top and appears the window that cause the lock. This is the only option I have worked for me.
Regards.
