I noticed that it doesn't crash if the '^' is in the first entry, but i've tested it many times, it is the '^' I think.

Do you mean the ^ character (ascii 94) or do you mean the symbol above ê. From the backtrace it seems that the crash occurs when you start editing a cell by typing a first character, is that correct? I can even use the upper left key on a German keyboard layout to generate ê without problems. 295776 3 annma 2004-12-19 16:03:39 +0000 Janno, what is your distribution? I cannot reproduce this bug, running KWordQuiz from source cvs HEAD. 350251 5 11448 cniehaus 2005-06-14 13:35:42 +0000 Created attachment 11448 This is what I tried This didn't make it crash 350253 6 cniehaus 2005-06-14 13:37:21 +0000 As I just stated, I could make it crash.
