We could check for this too, right? Ideally though, just editing currently broken-for-EXA patch so that it's only on when XAA is enabled is probably a better hack. Fixing it so it actually worked with EXA would be even better, but I don't think I'm up to that one :-) If Shawn doesn't get it done soon I'll try and tackle it myself. - David Nusinow -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
