Lately, it has gotten to where my middle mouse button is not allowing me to rotate my part or assembly. It started with larger assemblies - so I created a hot key on my keyboard for this situation. Now the middle mouse button doesn't work for rotating in any situation.
It still works for scrolling in and out (zoom), it just doesn't work for rotating.
Could setting a hot key have overwritten something that disables the functionality in the mouse? I know that seems like a far off possibility, but.....
I would much rather have the functionality of the mouse over the hot key.
