Platform: Vista64 Emacs Ver: 23.1.97.1 and prior versions Problem: I'll typically have 4 or more emacs frames running, then I'll open one more frame (File->New Frame), do an edit or search, then close the frame (upper-right X) and emacs crashes. The crash occurs randomly. Sometimes the emacs session has been running only 5 min, other times the session runs for 12+ hours. The call stack in Visual Studio is unhelpful with the pretest emacs version, sorry.
