Ajax ModalPopupExtender and Google Map

hi, there; using asp.net 2.0 (vb), i have placed a ModalPopupExtender on my page containing an asp.net panel and, within this, a google map.

first off, let me say that this map displays perfectly outside of the ModalPopupExtender however, when i place it inside and click the link to reveal the ModalPopupExtender, the google map does not display entirely (see image: http://www.gigantech.com/dkelly/modal.jpg)

i have scoured the net without much success but did happen to come across one poster who had a similar issue:

http://forums.asp.net/p/1091908/1848191.aspx

unfortunately, i am not using javascript as this poster is.  my data is pulled from sql server then attached via a procedure, to the google map.  that said, i still tried to use the poster's OpenModalPopup function but without success.

i'm wondering if anyone has had a similar issue or has any solutions to resolve what appears to be a bug.

thanks in advance.
