I have run a number of tests and have verified that it is running correctly. I'm switching over to it as I write this.

BTW, I haven't tested this on a P4, but I think it would have similar results. If anyone needs help setting it up, let me know. BTW, I have made a couple of changes to Phil's latest version of phrot that might be useful to anyone choosing to go that route.
Could you please email me your Core 2 Duo-optimized version of phrot? My email address is bugmesticky AT googlemail DOT com (yes, googlemail not gmail--I figured I'd clear that up at the start since people have gotten confused with that before. It's actually just an alternate domain for Gmail that I, for some wacky reason, was assigned an address from.).


P.S.: Your build of phrot for Core 2 Duo, is it by any chance a Linux build? I'd actually prefer a Linux build, as my Core 2 Duo runs Ubuntu, though a Windows build would be find, if that's all you've got.
