As a test I am trying to execute dillo (loads fast!) I setup cron as
user testbed to execute dillo every five mins,
I get the following ......

Setting locale to C

Gtk-WARNING **: cannot open display:

OK so i know its something to do with $DISPLAY, I tried setting
DISPLAY=:0.0 in a shell then execute dillo, no go ...
I know cron works AOK on non x programs

Can anyone advise ?

Normally an x program should obey to the -display flag for example if you 
switch to console, login as root and type
xterm -display :0
A root xterm should appear on you X display. I've tried it with dillo here but 
dillo just ignores the flag (not implemented yet ?). So try it with a more 
basic X application like xterm, xclock, xbill ;) ... those should work when 
you specify the -display flag but first test it from console to verify it 
works.

Many thanks, seems to work on simpler apps, not so on the big ones, ie 
mozilla ...
