I'm sorry you lost work. HyperCard's auto-saving behavior is hard to get 
un-used to and I think most of us HC converts have lost work at first. 
After a while you will remember to save periodically just as you do in 
other applications, but at first the similarities between Rev and HC 
make it hard to remember to do that.

You can put this in the stack script of your stack to simulate HC's 
auto-save if you want:

on closecard
  save this stack
  pass closecard
end closcard

This will save your work for you every time you change cards. I don't 
recommend using the script after you get used to saving your work 
manually, as it slows down operation somewhat, but for a while it may 
come in handy while you are learning.

A very good explanation of how Revolution groups differ from HyperCard 
groups is located in the online Help documentation. From the Help menu, 
choose "Search documentation". Enter into the search box: "groups and 
backgrounds". The last hit in the short list that appears should answer 
a good many of your questions. Rev groups can behave either like HC 
backgrounds, or like card groups. Once you get the feel of how it works, 
you will like it. :)

If you still have questions after reading the Help explanation, do write 
again and we'll jump in.
