Hey, I'm pretty much new but I have this one simple (or it may not be) major problem.
Whenever I do use the brush/eraser, any tool on the panel, there's this cross sign on them, say a rubber, there's a thick line over that icon, and you can;t use it. Happens to every other tools.
Secondly, when I use eraser, I try to rub it off but then the colours appear back up, ARGH.
ARGHHH, I'm trying out new things and they're making this stressy as hell -.-
Help?
Thanks in advance.
