Hello,
I don't know if this is of any help, but here is some data :

- I have been using MOI 4.0 for perhaps hundreds of hours over the last 2 years or so, on a windows workstation (first 7pro, then 10pro) using either a regular mouse, or a regular tablet (Intuos4 Medium), or a Cintiq (21UX black). I've never had any unexpected input issues on this setup.

- However, I also use a Macbook Air when I need to use MOI on the move, with a regular Logitech mouse. With this setup everything seems to be working fine at first and then some exception happens breaking the scroll zoom behavior of the mouse in MOI, forcing me to use a combination of mouse and trackpad for navigation. Since this isn't my main workstation I have not attempted to fully repro or document the issue, but something odd is definitely going on. Now this is of course different from your described issue, but perhaps this is related ?

I'd be more than happy to document the issue further if that's helpful.
