Forgot to say im an epic Ms Paint mindless fanboy.
In reality, I'd prefer any program having the "hold the left/right mouse button and while at it, instant undo by pressing the opposite one" feature, as well as the dual mouse button painting commands.
Other programs might have the fanciest of features, but if they lack the two I mentioned above, then I simply consider them obsolete. After all, everything I need to pixel is a good ol' brush and a trusty zoom.
But the problem remains unsolved -can I get my Vista back?
