Problems in changing brush sizes with keyboard

[brokk]

Hi,

I'm having trouble changing the brush sizes with the "[" and "]" keys, it doesn't work!
For typing the brackets, I need to have the alt key pressed down, I don't know if thats the problem. I suspected that it could be, but I couldn't find any way of changing it : S

But, I tried the same thing in Painter, and it works there. I have no idea why it works in one and not in the other.
What is even stranger, is that I'm working on an image in Painter, and suddenly the brush stops changing sizes by pressing the bracket keys. But, I open a new document and try it there, and then it works, and somehow it just "fixes itself".

What is going on? Any feedback on this would be really appreciated.

Compatability problems? If you resetted your keyboard shortcuts and it's still messed up, there's probably something wrong with your keyboard driver or something.

Oh. Looks like I'm going to have to reinstall the drivers then... ugh...

Thanks.
