Hello again,
Here's a modified version of the "mouse move triggers update patch".
This version generates a stream of updates as long as the mouse
moves. Although this uses more CPU, it updates more reliably and with
small timeout values produces quite smooth results when hauling
complex stuff around in CorelDRAW.
Cheers,
Mark
