I am using MPLAB-C 1.21, with MP-Driveway 3.0. When I generate the code, and try to compile it, the compiler bombs and locks up my computer. I haven't used these products much, but seems a bit excessive for a user interface. Any similar experience? Also, tried to get into AiSys's user community with a proper user and password, but IE3.02 locks up and I no longer have mouse support. Is it just me? John Craft. John A.
