Is this supposed to work like this: my configured middle click works only if I lift my finger up from the left side of the magic mouse and place it back down to the middle area.
If I slide/drag my finger from left to middle area (keeping contact to the mouse surface), middle click does not work, a left click will be performed. Touch live view shows that BTT is recognizing my finger to be in the middle area, but does not perform the middle click, if it's slided to the area.
Only if finger loses contact from the left surface an makes contact again in the middle area will make middle click working. Bug or feature? I think it's annoying, and would be much more comfortable if sliding the finger to the middle area would also work.
