Unable to attach file to create service notification(IW51) transactio iView

Hi,

We are using Create Service Notification (IW51) transaction iView (SAP GUI for HTML) in one of our portal workset.

Few users are facing issue while trying to attach file to the Service Notification. When they open the file dialogue to attach the file

it keeps on spinning and hangs, nothing proceeds further. Does anyone faced similar issue if so can you provide solution for this?

Regards,

Abhiram.
