The behaviour depends of the execution system the VIs are running in and the version of Windows.
Under Windows NT all VIs running in the UI execution system will stop working when you hold the title bar. VIs which are in different execution system will keep on working until they call a function in LV or a DLL which will run in UI Thread. serpdrv was discussed
here.
Under Win2K and XP the behaviour is different. I could not test it on consumer windows.
