(sorry for the delay--holidays...)

Well, I guess it's good it's just me--thought it was a pretty odd one. But I don't see any obvious rouge routine.

IDL> where(strmatch(routine_info(/system), '*test*', /fold_case))
-1

IDL> .run test
% Error opening file. File: test

I run a pretty vanilla IDL other than Astro routines and my library, which has no DLM--only routines and macros written in IDL.

I'll try it on my other machines...
