I just started playing WoW again after a while. One problem I'm having now that I didn't have before is that when I use the number keys to cast my spells, it's as if the shift key is pressed along with it. For example, I press "1" I get my spell. I press "2" I get action bar 2 rotated down, not the spell I had slotted into 2. When I type in my chat box, I get "1!" for 1, "2@" for 2 and so on. I can type any letter and not get the same issue.
