Quick Tabs in IE 7 and MS CRM 4.0

Here I am with another strange finding. We had several users reporting performance issues especially browser freeze happening while using MS CRM 4.0. When we ran performance monitors on the server, everything seemed to be perfectly fine. So we turned our attention to the client machines. After a lot of investigation into this problem, running Fiddler traces nothing useful came out. We then tried playing with the browser settings, disabling add-ons, playing around with tab settings etc.

Finally disabling quick tabs resolved our problem. We worked with Microsoft support but even they were not able to identify the reason behind this. However, here are the steps to disable quick tabs.

1. Open IE.
2. Go to Tools --> Internet Options.
3. In the dialog box that opens, select the "Settings" button as shown below:
4. In the dialog box that opens, uncheck the option for Enable quick tabs.
5. Restart IE.

Disabling this option greatly improved the performance for the end users.

Thats all for this post. Will get back to you all soon with more strange findings.
