Frequent crashes with 0.9.5

Sorry I can't give too much help here. What happens is that I set up a new score with many bars (say 90) and I'm writing the music in then I try to put a line break on a suitable measure and the program crashes. I think the message is that Musescore has asked the run time to terminate in an unusual way. When I reopen the program and my score (which I now always save before attempting a line break) it works fine on that line break on that measure, but it will crash later on.

Since it works OK when the program is reopened it clearly is not something in the score (and becuase it works OK on re-starting there's no point in sending an example). It seems more likely that the program is gradually corrupting in-memory data until it becomes critical, and the line break pushes it over the edge. Start again with clean data and it works. Wish I could give you more information.
