Dear Jeffrey, I hope you or someone else in this forum can give me some hints in solving my problem with a Kurta XLP 1212 graphic tablet and 3DS3. The tablet is in Summagrahics emulation mode (MM1201) after powering on and seemed to work with 3DS3 configured for a tablet. But I noticed frequent (once or twice per minute) cursor hang-ups after which the cursor usually works fine. If, however, a button click happens during this hang-up , the program and computer freezes and has to be rebooted. Using the supplied ADI 4.2 driver for the tablet shows to the same problem, only using the tablet in mouse emulation seems to work without problems. With other programs, like Animator, the tablet seems to work fine, even in SUMMA mode, so that I think this might be a 3DS related problem. The tablet connects to the serial port, from which it draws its power. Switching between COM 1 and 2 doesn't resolve the problems. The computer I am using is a 486/33 with 20 MB, 128k cache, 2 IDE HD's + floppys, WD Paradise 24 graphic card, Supra 144i internal faxmodem card, printer on LPT1. I would appreciate any advice for solving this problem or at least for explaining it. Thanks, Ulrich
