More on this, FYI. Conditions for crash here, by the way, Win XP Pro, 2G memory, IBM Thinkpad T41p.
The common theme is to bring up find window, then prev-Q window, using icons both times, then kill prev-Q, then kill find - die. It doesn't matter which sub-window you start in. It doesn't matter whether a search criteria or a prev-Q criteria is filled in or not. I did find two cases where it does *not* crash: Bringing up the two windows using the menus instead of the icons does *not* cause the crash. Bringing up find with icon, then prev-Q with icon does *not* cause crash. But bringing up find with menu, then prev-Q with icon *does* cause crash. Of course, if you bring up the prev-Q window first, it won't let you bring up search so no crash possible that way either.
