I seem to have increased incidents of crashing problems while editing in the score window since version 6 on OS X. I have 6.3.2 and it seems to occur quite often with files that have been updated from the previous file format. When I start a fresh new song, I don't have the problem. But I am now working on a piece with several song files where a lot of work was done last year in the older file format. This new crashing bug seems to occur when I select a group of notes and press the delete key to delete them. Then the program freezes and needs a Force Quit and Restart. Anyone else with this experience. Is there a bug in version 6 or the OS X implementation? Cheers! John Oliver http://earsay.com/
