Short description of error
Loop Cut Number of Cuts Wheel or PageUp does not work as expected, mouse wheel just does zoom instead of increasing/decreasing the number of cuts.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
cube->edit cube->press Loop cut symbol and try to increase the number of the cuts with the mousewheel...it does zoom.
