To invoke it you will have to get rid of any 'xwin' device you might have open and type 'Isys' (from the shell - it doesn't need ICL!). It doesn't have any contention with 'x2win', 'x3win' etc. - you can leave those in place.
If it crashes on you it may leave rubbish behind. Do a 'ps' to see if there are any processes that shouldn't be there, also do 'rm ~/adam/Isys*' and 'rm ~/adam/img*' to remove the 'rendezvous files' that it uses to communicate with Image Processing. Hopefully this sort of thing will become unnecessary or automatic in the future.
PLEASE LET US HAVE FEEDBACK!
