No - exiting the script and re-running it works. But - so does simply selecting a different computer! I'm thinking I have a problem in the WMIQuery udf that I downloaded.. I've turned on NoVarsInStrings and Explicit options, and when I regen any scripts that use the WMIQuery function, I get similar failures.. Looking into this more deeply now.

Already changed the $=Execute("$$...") line to use single "$" chars, and put the last var outside the string. That helped my small test function, so I think I'm on the right track.
