SYMPTOMS
When you use the ImgEdit.ocx control in a MFC application running on Windows NT 4.0, you may get a debug assertion in the RtlFreeHeap function when you exit a debug build of the application. However, when you employ the same control in Visual Basic, you do not encounter the debug assertion in RtlFreeHeap upon exiting. In addition, when you use the ImgEdit.ocx control in a release build of a MFC application on Windows NT 4.0, the control does not reveal this assertion. And the assertion does not appear when you you run the application on Windows 95, Windows 98 or Windows 2000, but appears on Windows NT 4.0.
CAUSE
This is a bug in the ImgEdit.ocx control. The assertion can be safely ignored because it is only given one time and that is when the application is shutting down. This assertion does not cause any problems when you are running in release builds.
RESOLUTION
Ignore the assertion as it is harmless in this case.
STATUS
This behavior is a bug in the ImgEdit.ocx control.
