I'm currently using an Athlon 64 X2 dual core 3800+, so I'm hoping dual 
threading will help. Really, any speed-up that you can give us is going to be

The biggest part of the problem is that it's the Batch window that's always 
active, so I can't click on the title bar of the main window to move it away 
from my Desktop icons if it's covering them. I've found a way to mostly work 
around the problem (by finding and opening the Desktop folder), so it's just 
one of those 'little awkwardnesses'. :)

Any chance I could help beta-test the new version when it's ready for testing? 
I have plenty of time on my hands at the moment and a dual-core processor, so I 
could give it a fairly thorough workout.
