Under NT4, sometimes kixref410 runs OK, then at other times it fails with the message:

Abort KIXREF: file not found.

For those files, the "type" command can find them, and that kixref gives an error message means that kixref is on the path. Kixref is somehow unable to work on them, even though it worked on other files in the same directory.

How can it be made to work consistently?
