Win7 64bit, GTX 560
Broken: 2.75 c6b042b
Short description of error
Sometimes when switching into the walk mode (Shift + F) in camera view the camera doesnot react to mouse movement. I found out that it is caused by fast mouse movement while pressing the Shift F combination.
Exact steps for others to reproduce the error
Open a new file, add a camera, switch to camera view.
Move your mouse quickly from left to right (or make quick circles with the cursor). Press the Shift F combo while moving your mouse. If you do it right the camera switches to the walk mode but does not rotate. The WSAD keys work as they should.
If the cursor is still during the shortcut everything works as expected.
