I have a 'mapwrap' div set to 400px x 400px and inside that I have a Google 'map' set to 100% x 100%. So the map loads at 400 x 400px, then with JavaScript I resize the 'mapwrap' to 100% x 100% of the screen - the google map resizes to the whole screen as I expected but tiles start disappearing before the right hand edge of the page.
Is there a simple function I can call to cause the Google map to re-adjust to the larger size 'mapwrap' div?
