* Run Terrain Builder - load test terrain of choice.
* Add an object - something like a fence section provides the most obvious example but any object will do.
* Launch Buldozer.
* In buldozer view - select the object, then attempt to rotate it...
* Now switch to 2D view and try rotation.. try Anticlockwise rotation.
* Now add a couple more objects and select the whole group - hold Left Shift and Right mouse button (rotate objects on their individual axis) - attempt to rotate clockwise and anticlockwise...
* Now hold down Left Ctrl+Shift and Right mouse button (rotate all about a central common axis)... There's a 50% chance of an outright crash at this point... If there's no crash, then again - attempt to rotate Anticlockwise as well as clockwise...
