Too much support

Well, Sometimes you just get too much support. How's that? Recently I began getting a pop up dialog that prompted me that the drawing I was opening had Mechanical objects that were saved to a version that made them incompatible. That is good info but I was using vanilla AutoCAD and I had never seen this come up before. It appeared from the command line to run a _amconsistencycheck command. I tried looking it up but to no avail. To make a long story short, I had added a new support path in my Options that pointed to the ACADM folder. Once this path was removed, the command did not come up automatically.
