bg 0 Posted January 28, 2012 I have been using Corel 12 with Signtools3(Asigns from Australia)bridge program, cutting sandblast stencil and vinyl with my desktop winXP, usb to serial cable, for 6 or more years. I recently upgraded to Win 7 and Signtools 3 won't run on Win 7 so, I ordered a new copy of Signtools 4 and Corelx4, not here yet. Win 7 apparently doesn't like some parts of Corel 12, but I don't know. I tried to cut a stencil today and the cutter would cut a few patterns right then it would do a crazy x-y runaway thing, drawing straight lines connecting other characters across the drawing. I assume it's a driver problem. I had to download the driver from this site because the computer wouldn't recognize any port for the Refine MH721 Any suggestion other than selling this piece of crap plotter?
