Thanks for the response Terry.

My customer gave me a update this morning, not all their computers have this problem. Only 3 of 10.

I checked with our computers in our office, only 1 of 6 has this problem. So it seems not every computer has the problem.

We use IE version 7.0.5730.11 and non SSL connection. Beside it's kinda strange, if we set UseStandardDialog to FALSE, then it works fine.

Also if we set the website in the "Trusted websites" in IE, then it works fine too.

I created a page for you to test it, wonder if you can reproduce it. Send you the info. in a email.

 

Thank you.
