So my copy of Photoshop is crashing on launch, and every copy of the Middle East Version of Photoshop does this eventually, (it's happened on 2 different comps now) Now I'm stuck with GIMP 2.

Big problem is that the mapping methods I use are primarily ones learned from Jezelf's tutorial a few years back with some of my own techniques thrown in. This means that the stroke tool, winch in Photoshop is invaluable for defining coastlines or edges, is now next to useless, as there's no option, it seems to only stroke the inside or outside of a selection, only along the center. Is this changeable?
