T&T: Offshore Navigator (Maptech)

[Seasalt007@aol.com]

I can't figure out how to automatically make the next chart appear when I  am 
creating a route. The book says double click the cursor at the edge of the  
current chart (when the little black arrow appears) and the next one will open. 
 I am too spastic to always do that correctly. My other navigation system, 
THE  CAPN, automatically opens the next chart by merely moving the cursor  off 
the edge of the current one and the new one appears. No clicking, in other  
words.
 
Is there a way to make Offshore Navigator do this?
 
Thanks
