Stripping the high bits fixes it. I tried to figure out why those got set in the first place, but was not able to sort it out. And since unsetting the high bits works I leave that unanswered. Once I fixed that I noticed that FvwmDebug didn't print the extended messages, because it didn't have showEvent registered as a handler for extended messages. /Viktor
