Hi there! I just found a reproducable segfault-bug in LyX-1.0.3pre2 (sorry, did not try the most current release -- perhaps later this day...). I create a displayed math formula. Then, within math mode, I hit 'M-e n' which is insert note (I use LANG=de). What happens is an inserted yellow "Note"-box in front of the formula (which is ok, I think) -- the formula itself gets left adjusted (although I made it display style, it should stay centered!). I enter a note and close the dialog box. Then the cursor is located between the inserted note-box and the math (math mode is left after inserting the note). I hit Backspace and LyX segfaults. When I insert the note outside of the math-mode, everything is fine (except the left adjusted display math, in the dvi file everything is fine again). When I move the cursor after erraneously inserting a note from within math mode, I can delete the note box with backspace later on without crashing LyX! So there are strange things goin' on (TM), hope you can come around with my description... But, again! LyX is great stuff and I really wonder, what other text processor I would use for writing my thesis with (I see all those cursing collegues using Word :->>>)... BTW: Is it really necessary to enable the note insertion from within math mode? Perhaps you could easily disable this option and everything will be fine (in fact I inserted the note erraneously and wanted to type M-e m, which is insert label in the german keyboard layout). cul8r, Frank
