I'm creating on WindowsXP a Projector (DirectorMX 2004) both for WindowsXP and
Mac Classic (9). It contains a button with a "go to URL" attached Behaviour. It
works fine on WindowsXP, opening a browser window which shows my local file
"index.htm". But the Mac version crashes as soon as I hit the button and
prompts an Error#3. It seems, Macs do not understand any URLs without "http://"
at the beginning.

Is this so? What can be done?

(Everything else on my Projector goes pretty well on the Mac. So maybe it's
not a question about authoring for Mac on the Mac, or is it?)
