[ SOLVED ] As I said long ago when I started this thread, I've worked in an IT department for over 15 years now and have been using computers and gadgets for nearly 30, and never has a problem vexed me quite so much as this one, but I finally solved it!!! The answer, hard to believe, was...my leather case. Yep, I guess the magnet was too strong on my case and when the screen would rub up against it weirdness followed. I've used such casees with touchscreen devices for years and never had a problem, so either the EVO is especially susceptible to this problem or the case I had was made by the devil, who knows. Hopefully anybody else suffering the same problem will stumble upon this answer some day and it will save them a lot of trouble! Thanks to all contributed for their time.
