ActiveX Property Pages May Appear Erased in Heavy Stress

ID: Q235700

The information in this article applies to:

SYMPTOMS

When the OLE property page of an ActiveX control is activated, it may appear unpopulated by its controls. The only thing visible are the tabs at the top and the standard command buttons (for example, OK, Cancel, Help, and so on). Clicking the empty tabs on the Properties page or clicking one of the command buttons may cause an access violation.


CAUSE

This problem is caused by a bug in Oleaut32.dll.
