sometimes after a game ends in counting and we both agreed which groups are dead, I get hundreds of identical error messages "Klasse nicht registriert" (class not registered) and I have to manually kill the process.

this started only a few weeks ago and could be related to me cleaning my w2k installation by removing remainders of old program installations and other 'unused' files.

anybody had a similar problem? Or any idea what the culprit might be?

Running on Wine, most of the buttons on the interface don't work for me and cause errors, but all of the important ones pertaining to finding a game and navigating through it are okay. I have not had any problems in scoring.

I also wanted to add that I played on WBaduk for the first time last night, 7 games. I'm playing in the low SDK range and I didn't encounter a single escaper or sandbagger. It was a lot of fun and I will play there more often.
