Wierd thing with AIM?

[James]

I got this IM out of the blue from someone on my list, when I clicked on the link my IM starts acting odd.

I got someone's away message that I hadn't sent an IM to . . . someone warned me that I hadn't IM'd at all . . . so I logged off AIM . . are there wierd programs that will make your AIM go bonkers?

ETA: If so do I have to reinstall the program?
