I tried this with IDL/v5.4.1 on my Alpha workstation, and had no problems. I
was able to make it work to five levels, at which point I stopped testing.

IDL> print,file_test('../../../../../.cshrc')

One thing you have to be careful about is that none of the directories can be
logical links to other places. For example, on my system I can do the
following

> echo $PWD
/disk1/thompson/temp
> cd ..
> echo $PWD
/disk10/thompson

If you were in the temp directory, you might think that .. would take you to
/disk1/thompson, but it actually takes you to /disk10/thompson, because temp is
really a logical link to a directory on a different disk. Is it possible that
this is what is causing the problem?
