Symptoms

When you use Visual Studio .NET with the MERANT PVCS Version Manager, you may receive the following error message:
Unhandled exception has been caught by the Visual Studio Watson exception filter
The exception occurs in the Ifc_com.dll module. Alternatively, when you use the Recalculate Hyperlinks operation in Visual InterDev or FrontPage, the system stops responding (hangs).

If you use a debugger such as Dr. Watson, the beginning of the call stack appears as follows:
IFC_COM.DLL+0x29b2

Cause

This problem occurs because the Ifc_com.dll module is a MERANT dynamic-link library (DLL) and is installed with the PVCS source control product.
