Since I updated to 10.4.6 on my Quad G5 I've been experiencing problems with TextEdit. Every time I type a dash, slash, quote mark, or any character that is not a number or a letter, if it is preceded and followed by numbers or letters without spaces in between, it turns into a double character. For example: 16-feb-06 turns into 16--feb--06 as soon as I type the f and the 0. When I try to delete the error the program usually stops responding and I can't type anything else anymore! Check Spelling doesn't work either (in any of it's forms). I have restarted several times and it won't fix it. This only happens in TextEdit, other programs are fine. This is really annoying, as TE is the only dedicated text program I have. I'm having to use Supercollider as a text editor now. Please Help!
