OCC crashes

Hi all,

I developed a 2D sketch module in MFC by referring to those example projects on this website. In my application, the sketch module is embedded in a modal dialog. The problem is that certain fatal errors may occur on a few PCs when the modal dialog is loaded. On most PCs the module runs well. My questions are:
1. what could cause this crash? graphic cards, OpenGL, OCC dlls, or something else.
2. if there any way to narrow down the reasons? many third-party dlls are used. That caused debugging to be much more difficult.
Thank you so much in advance!
