Centre Window Over Mouse Cursor
Return to DisplayFusion Scripted Functions (Macros)

Description	This function will centre the mouse over the mouse cursor, only if the mouse cursor is on a different monitor than the window's current location. Note that the window moves to the target monitor first, before moving again to its final location. I had to use this hack to make it work correctly when moving to monitors of different scaling levels. If all of your monitors are the same scaling level, you can comment out line 22.
