Program crash when activating hyperlink

[skendrish]

We built a "dialog-box based" program (MS C++) that is an ActiveX plug-in. We use a hyperlink to our company website in our program that works fine on the first try. But if we close the webpage and attempt to open it again through the ActiveX program, we get an error and the parent program attempts to save any progress then shuts down. The error message states that it may be caused by a stack overflow, out of memory condition or access violation. I'm at a loss as to why it works once or twice in a row then fails.

Thanks
