When I remove the plug-in It seems to run very smoothly.
**** I don't know if this has any impact, but I've read several places that the Dongle's LED is supposed to change intensity as you change the channels Intensity. Mine does not do this. I re-flashed the chip and received the correct checksum: OA6F. Are there any other diagnostic tests I can do to check if the problem is in the dongle, and how to fix it?
