Bug - Application Locks when user tries to move QDialog window

[SKolaMunn]

I am using QT 4.7.0 on a Windows 7 32bit PC, developing in MS Visual Studio 2008.

I have a QT application that opens a QDialog which operates as a video player. When playing the video (which uses a timer to update the QLabel displaying the current frame), if the user tries to move the window (by click and drag in the title bar), the whole application locks up. It unlocks when I press Ctrl-Alt-Delete to pull up the Windows Task Manager.

Is this a known bug? Is there a fix for it? If not, is there a way I can disable the user's ability to move the dialog during playback?

I appreciate any suggestions! Thanks!

Is this a known bug?

Its probably a bug in your code, so I don't think its known.

Can you show the code that manages the video and the slot that reacts to your timer for the frames?
