XML Coordinate File Access

We are having recurring instances of XML giving an error RE: not being able
to access the coord file as if it is read only. A program restart fixes it,
but it has been happening quite often. After restarting, I can do CFU to
see that it is accessing the file. Currently, I am working with Lot files
and it may be happening after a command is cancelled and then retried. It
then gives the error and requires the program restart to continue on. Has
anyone else had this occur?
