That fixed it. I will manually redo all of my settings, but in case it happens again, here is my old preferences file.

Thanks for your help!

If you provide the ini file with all setting you want /need restored and still don't have the issue, please share that too, for comparison

Well, it is definitely something to do with the way I set up my preferences. I manually changed everything back to the way I like it. The crash recurs when I repeat the above steps. Here is the new preferences file which causes the same issue.

Try step by step, amd save the ini before and after the crash.

I attached the requested files.

Additional Info

Tool windows that I have open include: Navigator, Score Comparison Tool, Timeline. I discovered that the crash does not occur prior to having these windows open. Also, the crash does not occur after these windows are closed and the above steps repeated. However, the crash does occur when the Timeline is reopened. Taking a guess, it might be a NullPointerException associated with the Timeline.
