I'd get all sorts of issues. Sometimes, you couldn't edit a line or it would refuse to list the program I had just run. Sometimes, you'd hit RUN and it would just sit there like a lemon. I bought and used MasterDos/MasterBasic as soon as they came out as they definitely helped as they patched a few ROM issues, but they certainly didn't cure the problems.
Resetting and reloading helped sometimes, others it didn't. On rare occasions, I had to abandon a save and go to a previous one. My big tip would be to save in rotation of about 5 files. If you need to, you can go back up to 5 revisions if things get really dire.
