IE6/IE7 FREEZE ASP.NET AJAX 1.0 IN ASP.NET 2.0 APP.

Question

Hello community!

I´m having frequent problems with Asp.Net 2.0 application that contains the following features within the same ASPX:

1. PageMethods Ajax calls.

2. ASCX who manage their own state, that is by buttons updated only content and this was handled through UpdatePanels.

3. Searches in grids in UpdatePanels within ModalPopusExtenders (being updated by a UpdatePanelExtender control, which allows from invoke javascript calls from the server.)

The problem is this, given some random called asynchronous (not repetitive steps are played) Internet Explorer (both 6.0 and 7.0) freezes, the application freezes and you have to kill process. (iexplorer.exe)

Try as solutions in the registry to change the maximum connections allowed by the browser by uploading them to unimaginable limits, but this is performed on client machines, the crashes are also appear.

So far the only solution that worked for me was to block the Thread (Thread.Sleep) for 500 milliseconds for each asynchronous call, the application works more stable but still contains the freezes ..

Any ideas or suggestions?

Really TKS!!
