Hi, I've been tryign to use Blender 2.37 ... and it's great except for one thing: When I try to select vertices, It seems to almost always select vertices that are nowhere near my mouse. Anyone else ever have this problem? I've searched and searched and I still can't find a solution.

Odd. I don't know if they've fixed it, but you can try upgrading to Blender 2.37a if that still doesn't work, report the problem to the developers.

I would also make sure that you are in wireframe mode. When in other views, it is very hard, if not impossible, to select vertices that aretoward the back or behind other sections. When in wireframe view, you should have a much easier time selecting vertices. Good luck.
