Due to the way Mac OS does focusing, an exitfield or closefield message 
is not always sent when the user clicks a button while a field is still 
selected. I had to work around this once by specifically sending a 
"closefield" message to the field before allowing the button script to 
execute. You could cycle through all your fields, checking their values, 
or you could do something like this:

   if the selectedfield is not empty then send "closefield" to the 
selectedfield
