Spells typing in the chat window instead of casting

[Rbwhite47]

Every so often my spells start going in my chat window instead of casting the spell. I can hit delete a few times and that works until I move, then it does it again. This is a real nightmare during a really heavy raid. Only thing that fixes it is to log totally out of EQ2 then back in. I keep thinking I must be hitting a series of keys without knowing it to cause this, but I can't figure it out. Any help would be appreciated. (Clean install done)
