Is the text kind of squished, making it unreadable? That's how mine is and I was told it was because of ISBoxer's instant swap. I forget exactly why it does it but, whatever ISB has to do to allow instant swapping causes it.

If it's the same thing, you should be able to disable the instant swap feature and have clear text again. I haven't actually tried it myself though, I just left instant swap on and learned to deal with the bad text.
