This has happened for over a year now. I thought that it was Amplitube 4 VST3 plugins causing the crash but after replacing all instances with VST2 versions it still crashes. Any new tools to read the mini dumps? I never seem to lose any data, but it is really annoying. Any suggestions for on line mini dump reader
Thanks in advance..... 

Just a workaround suggestion that works for me: Before closing Sonar, close the project from the file menu. If you haven't disabled the startup window, wait for it to appear, then close Sonar.

Thanks. I'll try that. I wish there was an easy way to read the dmp files though. Maybe I'll contact support. I hope tgst i won't be sirry sbout doing that. 

OK Dan, Tried closing the project, made things worse in a good way...... Now I get a fatal exception and it states that amplitube4.vpa is the offending module. More information than I has when I just exited  Sonar! Maybe I will try uninstalling Amplitube 3, or reinstalling Amplitube 4. Not my favorite way of spending the day........
