ITS - Screen Refresh

<b><b>Hello Forum,

Our Client is using ITS- 610 for R/3 4.6C and WAS -620 through Portal 5.0. The issue what they are facing is; the entire screen gets refreshes (Flickers) when the user move across tabs.

Did any one have this issue? If you have any solution or suggestion is greatly appreciated.

Regards

Guru</b></b>
