So everything works fine for me right now EXCEPT 1 thing in radiant. The 3D view works fine but when I move in the 2d view it GLITCHES OUT! I can zoom in and out fine, but when I right click and move, the whole grid just glitches out and goes all over the place  If anyone can help me it would be greatly appreciated.

Possible solutions:
1.) Reinstall Radiant
2.) Reinstall the mod tools
3.) Remake the map.

Something is wrong with either Radiant, the mod tools, or the map itself.
