VB6 caused an invalid page fault in module MSVBVM60.DLL at 014f:6604b3ce
I am having some difficulty with an ActiveX control (.ocx) I have
written in VB6. Often, when I have the control running on a form and I
close that form (or it's parent) I get the following crashes in
sucession (look below for the specifics of my environment):

==================================================
I attribute the second crash (SSSCC.DLL) to Source Safe.
Now if I run the same program on an NT machine I get the "the memory
could not be read" error, also when I attempt to close.
Here is my environment :
OS : Windows 95a (and Windows NT Workstation SP3)
VB : VB6 Enterprise SP2 with Source Safe 6.0 Integration
Project/Problem :
The control was written in VB and compiled. I am not doing any wierd
things except maybe rather large arrays and using the DrawText API. I
then drop the compiled control into another VB project (Standard EXE)
and sometimes (inconsistantly) when I close the form the control is on
(or it's parent form) it crashes. This happens BOTH in the IDE as well
as when it is compiled.
Things I have tried (without success)
- Compile in p-code instead of native code
- Looked for references not set to Nothing
- Removing the call to DrawText
- Adding the control as a project in the project group
- Applying SP2 (Our environment isn't suporting SP3 yet)
Sorry about the length, but I wanted to cover all the bases.
Thank You,
Jason
