I am getting this issue on Windows 7. I am having Quicktime 7.6.7 installed.
I create a QuicktimeMovie Component and load a movie.
When when i delete that component, i am getting a crash, It is crashing on the ActiveXControlComponent destructor.
I downloaded the prebuilt demo and tried the same, it crashes while quitting the application.
And Windows shows the crash module as QTOlibrary.dll.
