Unable to call QVW's in v11 with Ajax

[#1]

Greetings,

I just upgraded our Test server from v9 to v11.

The developers/testers are reporting that they cannot call a qvw from another qvw using the Ajax client.

They are still able to call using the IE client.

Has anyone run into this?  Is it a v11 bug?

Anyone have any ideas about what might be causing it?

Thank you for your help,

Don
