When you hit cntrl-M, you get the transform dialog and can type in rotation, scale, and translation. If I select a brush, hit cntrl-M, choose "move" and translate on the Z axis, everything works fine whether I use negative or positive values. But if I try to translate on the X or Y axis by a negative value, in addition to being moved in the correct direction by the right amount, the brush is ALSO being moved upwards slightly. Moving on X or Y by a positive value works just fine. I don't remember ever noticing this before. Is there a fix?
