So my wife and I went out and bought a Microsoft "Optical Desktop" (Keyboard + Wireless Mouse, with a fingerprint reader -- hey, it was on sale) for the Sawtooth she's getting in the mail tomorrow or so. I brought it home and hooked it up to my iMac. The "WTF kind of keyboard is this? Press the buttons next to the shift keys" dialogue pops up. The problem is that after a fraction of a second, the keyboard seems to "interrupt" whatever pointing device I am using... whether it is the MS mouse, my mighty mouse, or the numberpad keys. Anyone have any experience with a problem like this? Will a reboot fix it (haven't gotten a chance to reboot since I'm moving around about .5TB of files right now and can't interrupt it)? Are we just going to have to return them?
