In Modelbuilder 10.0, I am using Iterate Tables to iterates through some DBFs. Each one is to be appended to an existing DBF. The Iterate tool runs, but no follow on tool run. If I select the follow on tool, no matter what it is, and right-click Run, it runs correctly. For some reason, the follow on tools are not running until manually fired. All I do is select Run, no edits to anything. The problem happens when I choose Run Entire Model too - the Iterate goes but no follow on tool.
