@cadelaser77 Get a USB mouse, plug it in to one of the USB ports on your laptop (I'm guessing you have one, you said touch pad), use the mouse = Job done. Also, if it went oval, you pressed SHIFT or CTRL then scrolled. Or, you could just use [ or ] to change brush size, but remember to not use CTRL or SHIFT unless you want it oval.
+= Your very own USB mouse. Or, if you have brush shape issues then either scroll it or ctrl/shift-scroll it. If you can't draw elements, either prass the Caps Lock(if there is an [CAP LOCKS] text) or Insert(if there is an [REPLACE MODE] text) By the way, rule 3
