Hello Andreas.
I've had the same problem (I know this is two years later..
)
I downloaded CursorSense and yes, it still works! I enjoy having my mouse on very high sensitivity, and this allowed that. So please look into it and try to fix the BTT one. I've started a 20 day free trial on CS, but I don't want to be paying for that as well as BTT when my trial is over.
Please fix this!
Thanks
