I haven't ignored anything. I am just looking for a way around these problems. Sorry if
I didn't respond to each and every posting.

If you put half the effort in to working out problems that you do in complaining about
them, you would be a lot more productive person. I can't believe the amount of crap I
have received on this list. What's wrong with looking for a better way of doing things?
No one can tell me how much of a performance or lack there of this would have. If
someone came out and showed some results from doing this, that would be a million times
more helpful then jerking your ego off by badmouthing someone who is trying to learn.
