I'm not the type to return to a product page and run it down, but I thought I'd at least follow up for anyone else with this issue.
I was never able to find a fix. Frankly, it enraged me every time I wanted to select a block of code and was tossed into autoscroll mode. I could have dealt with if it had the sensitivity hadn't been so high so that a slight movement of my mouse sent me dozens or hundreds of rows away from my mark. This issue coupled with the insane way it handled tabs (really? When I want to indent or remove indention on a giant block of text it has to run through every line?). So the long and short is I had to abandon UltraEdit. I'm not going to seek a refund as it delivered what it said it would, just not in the method that was useful to me. However, I switched back to my freebie editor running in compatibility mode and that fixes several of the issues I had. They actually released and update after 5+ years of inactivity a couple of weeks ago as well.
Anyway, thanks a ton to those of you who took a stab at this. Goodluck out there!
