Thanks for the prompt reply, but after a few games of UT, a good nights
sleep and Re-RTM I realised the problem. The man pages clearly states
that the 'at' command doesn't export the DISPLAY variable when you
submit the request. I wrongly assumed it exported it at execution time,
which it doesn't. If anyone is interested just put the following line at
the beginning of your 'at' files to get them to 'xmessage' you.
DISPLAY=$DISPLAY
export DISPLAY
Cheers,
Matt.
