IRC problemm

I'm not sure why but my IRC does this every now and then but it won't let me connect to my BNC. It's because my User ID keeps changing on it's own every time i hit connect, which prevents me from connecting to my BNC because my User ID is my login name. Does anybody know why it's changing?

E: i've realized it changes on it's own just when i hit the OK button aswell.
