This weekend I built up a desktop from some old crappy bits in my garage and put a PCI wifi card in it. Lo and behold, scheduling on it was crap - it would totally screw up the first 1 or 2 accounts until the monitor finally woke up and then it would work like a charm.
So, I wrote a monitor wake routine into the header of the program and, voila, shes raking in the Bing credits! Scheduling should work much better now (especially if you have a shitty computer built from garage bits!).
