I'm running win xp pro with service pack 3, and Sigil. (0.3.4 QT 4.7.0) often crashes for no apparent reason (sometimes when I'm working on a large file, but sometimes with a very small one. When it crashes, a notice comes up that Sigil must close, and then it closes - usually without a chance to save what I've been working on. I thought perhaps my win xp had become corrupted so I did a full upgrade with my system disk but that didn't help. Next, I uninstalled Sigil and reinstalled it. Problem still persists...
What else could I try to eliminate the Sigil crashes?
