Back and Forward button disappear in SAP CRM IC

Hi Experts,

I am facing a strange issue which i suspect has some dependency on the IE or Java .

Please help me out if anybody has any clue on the same as to why is this occuring or what can be done to resolve it or even if there would be any logs registered from which I can find out what is the root cause.

Issue :

Sme agents when using the Interaction Center , finds their back and forward button disappears all of a sudden. There is no definite pattern happening, it could be like when they try to send outbound emails from a Service Request , all of a sudden the back and forward button goes away from the Email page.

Most of the times, it happens when they are trying to send outbound emails. But some instances have been reported even when they are in some other screen in IC and all of a sudden their back and forward button disappears. So they have no option to go back or forward using these buttons and only work around would be to try to End the transaction using the 'End' button and start over all again.

Appreciate any help if anyone has faced similar issue.

Thanks

Swapna.
