ComponentArt grid issue with Ajax call

Is there any special configuration needed to get the ajax callbacks working with the ComponentArt controls?  For instance, when I try to use the grid in the admin area to move through posts or comments, I get errors when I try to move to the next page of data.  Same code works fine locally.  Could be a proxy or firewall issue, I want to try from other locations to see if I have the same issue.

I have similar issues with the blog group page in the Most Comments and Most Viewed controls when trying to do the ajax paging.  I think this is CommunityServer code though.

Our configuration uses ISA server to forward requests, could this be causing the issue?  Any workarounds?

It is likely a firewall/isa issue. There are no configuration changes needed to support the CA controls.
