Thanks Paul for confirming that. Uwe is not seeing it under win 2000 so may be it is a Win XP related problem.
Yes, I get the same thing (on Win XP). I'm not positive, but I may have also had LyX crash when spell-checking a second document even if the first was error free.
At any rate, I've learned to close all but one document when running spellcheck.

I'll wait and see if anyone else confirms it on other platforms before i file a bug report.
