Hey, if you can figure out how to activating tapping, I'll be truly in your debt. Also, my theory on the random slowdowns is that it has to do with the virtual memory system. Usually, when I get severe slowdowns, its when I switch to an app htat I havne't used in a while, and have been running lots of programs (filling the physical ram) and that the slowdown relates to loading the program from the swap memory on the hard disk. I could be wrong, if someone smarter than I has a better answer, I welcome it.
