Also what version of Windows are you running (I'm too lazy to save and re-open your cygcheck, it seems Thunderbird doesn't think it is text)? And for the $64k question, do you use NTP? I have seen this sort of behavior before (on Linux, IIRC, but it might have been Windows): it can be caused by NTP clock slew. -- Matthew Congratulations! You've won a free trip to the future!
