How is that done?

Config menu then Ports and Pins, you will see all the kernel frequency choices.
It is usually best to not use more than you require but in your case you may find that 35KHz works better for your particular computer.

Okay, did it...  and the rapid speeds are now at 602... 
I imagine the cut speed will now be right too...

I'll let you know if not..

Thanks for your help, It's been a fun couple of weeks..   

I've still got a lot of stuff to find and copy over yet (all my fonts, my dxf clip art, etc.)
And then there's the 2 months worth of work I lost, and now have to rebuild all those files...

Gonna get the other computer working and all set up, and then I'll have a backup...
Thinking I might budget for a backup BOB and a spare gecko drive too...
This wasn't fun...

All fixed!
Thanks again!
