Unfortunately this forum is unique in that every thread is hijacked to become battleground for all sorts of great ideas, possibilities, scenarios, clever workarounds ...etc away from understanding really what the post wanted in the first place and in what setup and background they are working. If you look at fpga fora you will see spot on short answers most of the time and contributors do not spoil a good answer just because they want to prove they know better answer.

Hardly unique, and I think we often get the job done. Sometimes people ask simple questions to which there is no simple answer -- then, things get complex. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

That seems to be the normal evolution of casual group face-to-face discussions, too, so I've never thought it was too remarkable. I do think it's worthwhile to do something like Rick did, though, and make sure the OP got what they were after. Sometimes when you do that the OP has long since disappeared. I don't know if that's because they got what they wanted and left or they got annoyed at the digressions. This place can be interesting sometimes. ;) Eric Jacobsen Anchor Hill Communications http://www.anchorhill.com
