How to speed up Scan in Widows 8.1?

[mancunian]

This is brilliant thank you much quicker but I get an error "invalid argument" when I try and scan for the colour black using QM version 2.4.3.0 but it worked okay on 2.4.2.2



RECT r
r.left=1; r.top=1; r.right=100; r.bottom=100
scan("color:0x000000" win r 0x1000)
