hi the problem i have is this: sometimes i will find that the keys on my keyboard have switched. what i mean by that is, if i type a letter, another letter appears. obviously this is a huge problem. when i close the program and reopen it is back to normal. i have a wireless keyboard and mouse but this letter switching only happens in one application at a time, regardless of how many i have open. (eg. if i have firefox, msn, and limewire, only one will switch, while the others still work) i have no idea what the problem is. please help!
