[App_rpt-users] URI active low?

[Steve]

Being pulled low enough is kind of what I was thinking and wondering if others have had that issue.  Its really the only thing that makes any sense to me in terms of what I am experiencing.

A little digging shows this solution, which I will try this weekend once I dig out my parts.
