Page in Modal Dialog Goes Blank

[adam]

I'm writing an Intranet application that uses Modal Dialog boxes and
have embedded a page within an iframe on another page that is opened
modally, so that the postbacks work as normal. When running the page
locally, it works perfectly, executing the code when clicking on a
button and then redirecting to itself to refresh the page display.
However, for some reason, when I run this on our production server,
although the code is still executing (the results can be seen
elsewhere), the redirect doesn't seem to be working and the page goes
blank.

Any thoughts?
