What Am I doing wrong here, ;) I am using all features EXCEPT the programmer on two different NT 4.0 Machines with SP3. Absolutely no problems. I haven't tried to use the PICSTART PRO with NT because it did not work on pre 3.4 MPLAB VERSIONS & I just leave it hooked up to a win-95 machine and transfer the files across the network. Everything else works including the simulator. Just my observations. 73, Dan Welch w6dfw@qsl.net
