FRAME trouble

[Richard Dixon <rdixon@xxxxxxxxxxxxxxxxx>]

Dear All,

I was wondering whether anyone might know the source of this problem that
appears to have cropped up randomly - I've used the procedure below many
times with no trouble. I'm running ferret using the

ferret -gif

command - however when I come to produce a hardcopy of the graphics using
frame, I get this error: 

**ERROR: invalid command: No open workstations for batch FRAME command

Many thanks for any help,
Richard
