I had patches uploaded to the dev repos which disable the font updater for 3.21 because it has it's own font updater. It's also the only version of SCAR that will able to cope with fonts with shadows added which will be added for the new OCR in SCAR 3.22, I'll look into the problem for you though. After all, I'm still part of the team
EDIT: Apparently I caused that bug, I always use High or Length statements when I'm looping trough arrays in case I change them later on, I didn't notice that that wasn't the case for Markus' code, he used static numbers, so when I removed TradeChars from the arrays it kinda died, I'll have someone upload my patch.
