Title: Fix x/y calculcation when hit testing form on multiple monitors

As stated in the documentation:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms645618(v=vs.85).aspx

**Important** Do not use the LOWORD or HIWORD macros to extract the x- and y- coordinates of the cursor position because these macros return incorrect results on systems with multiple monitors. "
