Bug? Random missing characters

Every now and then I seem to have a couple of characters disappear when loading sketch files. Often at the end of a line, sometimes including the carriage return.

I find this when compiling and parts that compiled fine dozens of times before suddenly get a strange error - often a missing ";" which should have been there before, sometimes code is found at the end of a comment , which is missing a couple characters. One time even the (){ from the end of the 'void loop(){' line was missing.

I've only seen this in the beta.7 version. If it happened in versions 2-5 (I didn't try 1 or 6), I didn't notice it.

I do like the look and feel of the 2.0, hopefully whatever is causing this bug gets addressed!
