--- Comment #3 from Simon <sim...@smcalister.me.uk> --- So I have gone back to a saved file a few weeks old and started updating it with Calc v 7.3. The same thing happened, a crash, recovery, and weird stuff happening within minutes. Tried the same with 7.2 and similar thing. No obvious trigger for crash, was doing different things. Each time tried the simple example formula from first post (cumulating) and got the fixed result of 2 when copied. Then I installed version 6.4 and was able to update without problems, so far about six hours of work without a problem. So it points to a bug in version 7. Its not a good thing when CALC cant calculate the simplest formula! So lesson learned, to save files more often - I used to but got blase with problem free running for the past couple of years. It is a weird bug - even =NA() was returning zero. Entering a formula worked, but copying it was the problem. I have the corrupted file if anyone wants a look, it is big though at 2.5MB Simon -- You are receiving this mail because: You are the assignee for the bug.
