Working off IIS 7 with an asp.net mvc app.

Most page accesses are lightening quick. Sometimes the browser reports 'page loading' for an exceptionally long time. We are still in the development/testing mode so it's not a network/bandwidth issue. Happens in both IE and FF. No explicit error conditions in the server logs.

If i could reproduce it i could run firebug/fiddler to give more info. As it is, it's a little too infrequent to simply leave both those running hoping for the condition to fire - unless/until that's the only option to get better info.

I have a hunch this is client-side jquery/ajax related but only a hunch - don't have enough background in either jQuery or MVC to really know what can go wrong.

Any initial troubleshooting suggestions welcome.

thx
