Fix T84645 cursor moves when clicking selector. 

The absolute position desktop mapping has been corrected. The correct
mapping is 0-65535 inclusive. Additionally, division by the virtual
desktop width and height needed to be subtracted by 1 as width and
height are one more than the final pixel index.
