Cancel the good news. After working on modifying some performances the crash has happened yet again. It is making dragging and dropping into a performance almost impossible and if it doesn't crash it does not always save. I have spoken to support and it is a known issue, which is a relief as I now know that it is not just me.
The same thing happened to me ... I created a "corrupt" performance, and could not delete it without crashing my toaster.
This morning I did a factory reset holding down system button at startup.
Downloaded and installed latest "stable" OS & RM.
Then in browse mode I was finally able to remove corrupted performance.
Seems fine now.
I was never a big "give me an editor" dude ... until I used it. Very useful !!
I'm not going to reinstall it right away though ... I can wait for a final release .
