Data Execution Prevention Rant
Yesterday when I attempted to open an Autocad drawing, Autocad LT 2006 repeatedly crashed with a "tried to access memory at location 0xYYYYYYYY, the memory could not be written". I tried a couple of other files, and also rebooted. Same thing.

After a half hour of messing with it I found the exception I had set in DEP for the Autocad executable had been deleted. I had put it there because Autodesk tech support instructed me to, because Autocad LT 2006 will not run on some computers without it.

So how did my exceptions in DEP get deleted? Is IT screwing with my computer again? Or did a recent Sophos AV or Microsoft update do it?

I would bet on a recent Microsoft Update.
