I just checked this link out.
From what I read, it's a much more verbose solution and the onlyadvantage I see mentioned is that it prevents the user from dragging an object out of bounds (whatever that means -- out of its intended target? Off the card?).
Am I understanding it correctly?
Continually polling the mouse location in a repeat loop uses up a lot of system resources. In MacOS (before OS X) it wasn't as big a deal because the Mac didn't really multitask and so you weren't holding up any other apps very much by hogging the event queue with a long repeat loop. But on all other OSs, tying up the event queue with non-stop polling can cause problems with other background tasks. The more efficient (and Raney-approved) method is to use built-in Rev messages to do the polling for you.
I explain it more here:
