Apart from the issue Dave mentions, the only time I have seen anything
similar to this if the system disk is full. findfile() spawns a ls process
to get the file list, holding it in a temporary file on disk. If there
isn't sufficient space on the disk to hold the list of files the results
from findfile() are somewhat random.
How full is your system disk?

Are you sure you have IDL in the directory you *think*
you have it in when you issue the FINDFILE command?
That is the only reason I can think of why it would
work one day and not the next, .... unless. You don't
happen to have a wooden cross and a handful of
garlic handy, do you? You may need it... :-(
Cheers,
David
