So I use a small Wacom tablet to draw in Illustrator and I've always run into a small, but annoying problem.
I do a lot of tracing so I often can't trace something in one fell swoop. I'll usually just select the path I
just traced so I can continue and the new path will just be added to the new path. However, much of the time
instead of adding of that happening, the previous path will be deleted. If I command+Z it and retry sometimes
it will work the second time, but most of the time it will just happen all over again. Anybody have any idea as
to why this might be happening? Could it be an issue with the tablet? I'm stumped...
Double-click the Brush Tool and uncheck Edit Selected.
