A customer called to report that his Softimage crashed/froze at startup when it tried to display the OpenGL viewports. This is the classic symptom of a display driver problem, and the hide-the-OpenGL-viewports test seemed to confirm this. But reinstalling the display driver didn’t help (Softimage was working just the other day, so the same driver should work).
Using Process Monitor, I was quickly able to track down the problem to the Wacom driver. After he reinstalled the Wacom driver and restarted, Softimage started up again. Watch the video to see how to quickly find a possible problem in a 200MB log file with 845,000 log entries 😉
