Well, I tried modifying the ledcontrol.vbs with the LedControl.FastCom option, but it seemed to screw up my ledwiz port assignments. It's not like a shift in assignments either. One time I loaded the table, my RGB strip turned red, then another time I started the same table, it was blueish/green. Normally the strip is set to Blue for the table. As soon as I commented out the LedControl.FastCom option, everything returned to normal.
I really hope we can figure out the delay issue. It would be great to be able to use UVP with the ledwiz.
