I do have UAC turned off; while I can turn on CursorXP, my problem is that within about 10 minutes or so of turning it on, the cursor gets jumpy. I'll try move the cursor, and it will take a little to actually catch up with with my request (sometimes as long as a full second). Once that behavior starts, it doesn't stop until I disable CursorXP, restart Vista, then turn CursorXP back on. "Regular" cursors don't do that.
I may not have a computer with the highest specs in the world, but they're much higher than necessary to run Vista Home Premium and a bunch of other programs at once. I've tried futzing with as many settings and programs as I could think of, done a lot of web searching, and even tried using a diagnostic boot to try to find which program might be interfering with CursorXP. I'm stumped. Does anyone have any ideas?
