problem on webdynpro running in the same window with sap-portal

Hi

I have a strange problem -

i working on my sap portal while loging-in with my user - ami1

and executing a webdynpro application from my SharePoint Portal, the WebDynpro has a generic user that is loging in to the sap system - i configered it in the SICF transaction .

The wd application is open automaticly in the current IE which is open but in a new tab ( the IE ia already running sap portal ) and the wd application is stuck and not running. If i am closing all the ie windows and run only the wd application it runs ok and the display it correctly.

For my opinion the problem is that i m running 2 tabs but with different logon - is there a way to fix it ? to deal with this situation ? and doeas it sound reasnable ?

Thanks Ami
