Editor issues

Every once a while I get to the point where I need to restart SC or the browser because the editor gets corrupted. The line numbers overlap the code making it unreadable. IT happens at least once a week. So far I was not able to find the pattern or what is causing it but it is something thet needs to be addressed because I have a feeling like it happens more and more often.
