Buttons work slow when I hold them.

I hadn't had this before, (I've installed windows 7 on this machine before), but for some reason when I reinstalled it again this friday I now have a weird button problem.
In a text area, whenever I hold down on a button (ddddddddd kind of thing), hold down the erase button, or use the arrow keys to scroll through the text horizontally, it types/erases/scrolls really slowly. Like... it doesn't go fast, but very slowly.

Here I have recorded a 36 second video of the issue demonstrating it. Dont worry it isnt conficker or anything, it's IOJ, a very useful uploading tool for window to take screens/videos easily.

Take a look. It's fairly annoying, I use the backspace one a lot.
Oh also, using arrow keys to scroll through the page is also like that. It applies to anything that has to do with these buttons being hold down.
Does anyone know how to tweak this?

 

Nevermind... for some reason they work fine now. Sorry, I guess restarting worked.
