Thanks for the feedback about setting the userlevel. I still haven't decided
what I should do but at least now I've got some more ideas to go on!

Another thing I would like to get straight is the problem with visual effects
that don't work on the MAC II. (I'm talking about "visual effect dissolve"
etc). I don't have access to one so I can't test this out but I believe its 
got something to do with the depth of the bit-image, or maybe wether colour is
on or not ?

Specifically what I need to know is: Can I set the graphics mode of the MAC II
from hypercard so that the visual effects WILL work, and if so how. Do I need
an XCMD or can it be done by HyperTalk ? I've never seen this mentioned in any
of my HyperTalk books so I assume it will require an XCMD. A simple
alternative might be to detect that the stack was running on a MACII and tell
the user what to do to get the visual effects working.

Thanks in advance,
Mail me and I will summarise,
