I wrote a big program last summer, using MPLAB 3.09, and simulating a couple of dozen routines individually. I dropped the project for a while to work on another, and in the meantime downloaded and installed 3.12. This past week I went back to the old project and started trying to integrate the pieces. Now the simulator bombs instantly, telling me there's no debugging information in the project! What do I have to do to get back into the simulator? john perry jperry@norfolk.infi.net
