[issue #41] XClick dual monitor support

If you only use only one monitor, it still works normally. I have the same problem when using a second monitor (windows 10, Extend monitor)

Video screen capture
First time, use 2 monitor at the same time -> error (at 00:00:30 look at 2nd monitor)
Second time, only use one screen -> it’s ok!

Thanks for the detailed error report. => I added dual monitor support to our todo list for this quarter.

Ahhh, I was wondering why all my XClicks weren’t working. Good to know. Glad I stumbled upon this as it was driving me crazy trying to do simple XClick commands. +1 to implementing dual monitor support!
