Broken: 2.70 and latest SVN
Short description of error
Changing multiple axis at the same time with the new click-drag function works for Scale but not dimensions.
Exact steps for others to reproduce the error
Default scene, Click-Drag mouse on "Dimensions" in the N Panel to change (x,y,z) at the same time
Enter 2 for example
Result: Doesn't work, 1.000 stays.
Sliding left-right only changes x and z not y.
