> My emails and 'private threads' - about a certain bug I found - to him were not answered at all (like sending something to a black hole indeed). I'm not sure what to think of that. My initial feelings are that it's simply impolite and arrogant of HIM

You assurred no guarantee of a response if you send private messages to anyone on the VFP team. We get busy, and sometimes things slowly sink to the bottom of the inbox, and get forgotten about. I'd like to think that it doesn't happen often, but I know it's happened to me. You also might consider that BillG does let us take vacations once in a while. :-)

I try to respond to every message, but sometimes I simply don't get around to it. Your best bet is to post it to a public forum such as the UT, where you will more than likely get a response from someone else, or a Microsoft person may chime in if they feel they have something to contribute.
