Frankly, i'm rather confused, what with all the recent 'progress', about what is safe to patch anymore. anybode got a good summary of recent patching zen?? Also on this question: I'd like to intercept all attempts to read or write from the .Aout and .Ain drivers. Is it kosher to simply patch their unit table entries? what I'm worried about is these drivers getting a CloseDriver from somewhere after patch time.This would invalidate the entry, and might crash the machine, if it releases my patch instead of the driver! Anybody dealt with this before?? -JT
