This issue I'm having is making work VERY hard, I hope someone can help. When I'm typing the code it will at some point (every 5-10 minutes) scramble itself, syntax colouring is messed up, parts of the words are missing, it automatically moves my cursor to somewhere else, I can't read things properly, and undo/redo screws up, etc. The easiest solution is to select another file in my project and then the one I was having trouble with, unfortunately, it can sometimes happen very often. I've even had an error saying something about an index (from xcode) and asking if I wanted to continue or quit. In fact, I've actually found xcode is modifying some of my code elsewhere, just little bits. So, when I compile, I find I have 9 new errors or something from code that I haven't modified since I last compiled... which is very unproductive, fixing errors that shouldn't exist. Any thoughts?
