OK, using info from some of the other posts here, I uninstalled DS 2.6, installed the Microsoft DDK, and Symbol files, ran the debugger from the ddk and then reinstalled DS 2.6. Nothing has changed, Softice still has same problems as before. Can someone explain exactly what Softice actually needs. With previous Windows OS's, I never needed the DDK, or symbol files. I just use Softice for application level debugging and not device driver stuff. Is the DDK or Symbol files needed for this type of debugging? The only thing I saw in the DDK that looked like it might affect Softice settings was the global flags settings, and I tried many different settings without resolving the problems with Softice. What exactly am I supposed to do with the DDK, other than installing it?
