I haven't a clue what the problem would be, but certainly you could try to track down the problem further. Subclass the window and override -close and -dealloc. Put breakpoints on them and reproduce the problem. See where they're being called from. The stack traces should, hopefully, tell you what's causing the window to be closed.
