You've probably got the mouse and keyboard too far from the transmitter. I bought a MS wireless keyboard/mouse combo and had the same problems. MS wireless devices seem to need to be extremely close to the transmitter, I'm talking 2-3 feet. Logitech products work from a far greater distance. Try moving the keyboard and mouse very close to the transmitter (couple of inches) and see if the problem goes away.

Strange. I downloaded Console v2.00 beta 142. When I run it on Vista SP1 it opens, but the text appears to be black-on-black. Setting the font color to white or any other color doesn't seem to help. Not sure if it's just me or not. Is KDE required? Sourceforge screenshots look great though!
