- install x-button mouse control
- set middle click (or any button you desire) to actually do a left button click
- go to the microsoft mouse and keyboard application
- set your desired gesture to trigger a middle click - or your custom action if you specified one in step 2. (x-button mouse control will override and do a normal click)
issues: -you lose a button since you are overriding one -tap and hold still doesn't work (i.e. drag and drop is still not functional)
