Hi guys, I really like paint.net, but i make a nOOb error that i don't know how to fix. When you open the program for the first time, you have a number of panels on the screen. On the lefthand site there is the panel that allows you to choose the different tools, on the righthand site there is the "color" thing. But i kinda closed them and now i have no idea how to open them again! Haaaaalp!
