I've had both problems that Flight just described as well. I've also wondered if the ESC thing might be the cause with it counting them over time and not resetting the count if they aren't all quickly in a row. <Shrug>

I thought it might just be my imagination with the cursor skipping the middle monitor sometimes, but that does appear to happen. My setup is the same with three monitors in a horizontal row and the middle being the server.

Just chiming in that I've had the same problem.
