Now, I consider my self pretty computer savy, but this just has me confused I recently had to do a format, reinstall on my moms computer. Installed windows xp, service pack 2. Installed avg antivirus, adaware, and some other programs that she uses for her business. I got to the point to install her wireless keyboard and mouse (logitech mx700) I hooked up the keyboard, mouse and reciever, windows dectected it, but it wouldn't work. I thought, well thats wierd, so I pulled out the CD, loaded it in, and it started up, then a big nice fat windows error box pops up and says "this software is not compatible with your operating system" wtf...... so i head over to logitechs website and download the windows xp install.....same thing...im at a loss
