Set your computers up on a network and then leave the dongle in one
computer. This way it will eliminate the need to move the dongle back and forth. You will just need to remember to close Flexi when your not using it.
I do all my designing on my Desktop that is built for performance & design with the 23" widescreen. I do all my cutting/printing from my laptop. I have them both networked and keep the dongle in the laptop. When ever I'm done with Flexi on either machine I close it.
