Well... here's what I've done now.. and it seems to work great, except for
www.youtube.com in classic mode. I've removed HTC Task Manager even though I like it, AND FTouchFlo from the rom. I flashed the new rom and then installed SPB Pocket Plus 4 into system memory. I only included scrolling and core files (this includes "X" close). This seems to work without conflict, aside from hanging Youtube. Not sure why this happens. Other websites scroll just fine and the x closes all files. I'll live with this until someone comes up with a better solution.
I decided that even after editing the _FTouchFloconfig.txt file that the scrolling app wasn't as fast (and I didn't see panning) so I had to let it go.
SPB has a good thing going here... wish they would just package the scrolling feature by itself for purchase. I'd be all over it.
