Atlas and asp.net Image control not refreshing (firefox fails, IE6 works)

[PeterKellner]

I have an asp.net 2.0 Image control that I have surrounded with the
appropriate atlas:UpdatePanel tags. The Image control referencs an
aspx page whose only job is to output an Image. (it forms the image
in it's page_load and ultimately writes it to Response.OutputStream.

In IE6, each time I cause a postback, the image is updated as I would
expect. In firefox, the image does not get updated on postback until
I force a refresh on the page.

Thoughts as to why or how to fix? I'm using the April Atlas CTP.
