Modal popup and Gridview.OnSelectedIndexChanged Firefox problems

Hello there again!

I am building a gallery for a site and I am using a gridview to do this. The idea is to have a GridView which shows the gallery items, the user clicks anywhere on a line in the Gridview and a ModalPopup pops up to show the gallery item's details.

I am however encountering two problems:

1) The ModalPopup is somehow increasing the size of the whole page (Scrollbars appear or get larger) which causes it to center wrong and gives problems dragging it (While dragging the scrollbars resize which offsets the dragging and it ends up at an other place then you wanted it).

2) The ModalPopup is not being shown at all in Firefox when you click the Gridview. The Event fires, and it gets inside the if statement, but ModalPopup1.Show() simply does not work.

Any ideas?

I can answer the FireFox question - Modal is broke with Firefox 2.0.0.2 (prev versions should work fine) MSFT and FF are supposedly working together to resolve the issue...

Your other issue is most likely how your CSS is structured...causing the scrolling... setting explicit width and height in pixels may resolve the issue. Considering this is displaying images - if the images vary in size could possibly end itself to this particular behavior...

Well, that wasn't really the news I was hoping to hear abour FF... Is there any ETA on the fix, or is it such low priority that we can wait forever?

The CSS I am using is the following, the images will be having a fixed width but variable height:

.ModalPopup
{
width: 750px;
background-color: #E6E9EC;
font-family: georia, serif;
font-size: 12px;
text-decoration: none;
text-align: left;
color: #000000;
border: 1px solid #CDDFF7;
}

I don't really see anything wrong with it other then setting no height, so I tried setting it but it still showed the same problem.
