OK, thanks for your suggestion about checking the system log then - I will look out for that. > With puzzling, intermittent errors like this, I often find that reading your > own code carefully may be more productive than going to heroic debugging > extremes.

That's a fair suggestion, but taken in its most general sense that is a near-impossible task. There are 100-odd source files in the project, etc, and just "code-read the project and look for some bug" is a non-starter. Are you effectively saying that you agree with my hypothesis that the cause is GUI-related code being executed on a non-main thread? If you or others have definitely seen that cause problems of this sort in the past, then I'll certainly do a second more thorough read-through of any code that could possibly be relevant...
