Incomplete map in IE6

[AlaskaTom]

I am using Google Maps Pro to pull in multiple locations from a recordset. It works great in Firefox, and Safari, but in IE6, the map often only half loads. All the pins will be there, but only half of the map will load.
Has anybody else seen this? and is there a fix.
Here is an example.

Thanks!
