Master Page Header Design Issue

Migrateduser

<p>Does anyone why my master page header gets cut off when I'm designing it?  When I run the report it displays fine but when I'm designing I keep needing to change the header size from .5in to 2in so I can see everything in the grid then I change it back to .5in before I run it.  I know there's a way you can see everything while you're designing I just forget what the setting is.  See pictures for examples.</p>
