I have recently installed lyx1.6.1fix1 (on RH 7.0) from binary rpm which I got from the lyx website (.. actually from a sited linked from the lyx site). I read through the bugfixes for 1.6.1fix2 and this nasty bug is not included there. So please read on. Here is the problem: If there is any evil red text (ERT) in math mode, on save lyx crashes and both the original file and the lyx.emergency file are saveed incomplete. I had to fish pages of work out of the core dump to restore my work. The error can be reproduced as follows. 1. Select File->New or open existing lyx file 2. Within the document switch to math mode and type "\sin (x)" or any other expression containing \[some tex] that will display as ERT. (e.g. \omega will not result in crash) 3. File->Save will crash lyx and destroy some or all of the document (both the original and the .lyx.emergency) Since after the crash most of even previously saved work is destroyed, this bug makes lyx1.6.1 unusable. (I do use a fair bit of ERT.) I don't want to sound ungrateful, I appreciate all the work you guys are doing, and lyx has been good to me till now (crashes yes, but no work lost), but please put future versions of lyx through more testing before releasing them as 'stable'. For now I'll go back to 1.5.1fix2 which has not given me much trouble. I guess I should always stick with the highest fix-No. previous release. Would it be correct to assume that they are/will be more stable?
