Several newbie questions & a documentation request

Thanks for the replies, but I got rid of most of the weird behaviour by 
making a new stack and copying across all the necessary buttons and 
fields.  As this was my first stack after the Hello World there were a 
lot of half-existing groups and so on that hadn't been deleted properly.

This is now working fine, especially after I deleted the first "/" from 
the file path before replacing with ":" for the AppleScript.

As mentioned above, this seems to have been a problem with a really 
messy stack.

The 'recipes' in 2.1 help with this as you get more examples of how the 
grammar works than in the tutorials, but a list of specific differences 
would be nice.  I'll keep notes of the differences I come across and 
post it to the list and to the feature request address.

For now I've downloaded the 30-day trial to test this out, it seems no 
faster but is much 'prettier' as you miss out on all the flicker.
