We get complains that some customers have problem with the "Upload" buttons in different dialogs in IE. When they click on it, no browse window will show up. So we updated to the latest build this morning.

But now when they open the dialogs, they all get a security risk message from IE (image, flash, media, etc.), something like:

This page contains some possible security risks. Do you want continu?
(You will get this message 3 times when the dialog page refresh!).

 

I check the configuration, you will not have this problem when you set UseStandardDialog="true".
We don't want use this because the transparent DIV is not well implemented. When you have a large page with scrollbar, the DIV element is  too small and will not cover half of the page.

 

Anyone knows what can cause this?

 

Thank you.
