Seriously people, cut Jens some slack. He's making some damn fine products for a computer system that been out of production for a long time. There will be teething problems and I'm sure Jens is working on them as long as such problems can be reproduced.
I have myself nearly gone bald, pulling my hair out trying to figure some problems out with my Amiga, but stick with it - it's part of the fun, when you finally get it working! Time and patience is required for these old gals
