Try to narrow down when the crash occurs. Is it some page getting loaded? Clicking on an image? In our case, we were able to avoid the crash by pressing the browser reload button before pressing the button on the page.
Also make sure you can reproduce on more than one machine. I often see problems such as you are describing that are due to a bad DLL or file version.
