mm, I'll try unplugging/replugging it next time I need to do something.
And I'm talking about a regular tablet, IMI or something - not wacom.
I'm in a pickle.. I use Gimp to shade things and Paint.NET to color them (it won't work vice-versa; I find it a lot easier to color in Paint.NET).
ah well, i'll try the unplugging thing later on, when I can restart my computer without losing info.
EDIT: Unplugging/replugging works, thank you.
