So I've been using X5 on Windows XP for quite some time now and everything worked great. I recently made the move to Windows7 and now I have a minor issue. When I draw any geometry on the screen I can't visually see anything being created, but after create say a line, and then move the scroll wheel, the geometry will appear. Also when I used to pan over an entity, it would highlight to be selected. It no longer does this.
Any ideas?
