Hi Andrew,

A couple of things:

* The value of "it" does not persist between handlers; so having the 
dialog OK button script place a value in the "it" variable in its 
handler does NOT affect the value of "it" in the mainStack keyDown 
handler.

* Be very careful about placing a "debugging" answer command after 
any command that returns a value in "it".  Example:

	answer file "What file do you want to open?" -- "it" now 
contains the file path
	answer  "You selected"&&it -- for debugging
	open file it --the value of "it" is now "OK"
