CRM_UI_FRAME brings a blank screen

Hi,

after installing CRM 2007

and starting ...8010/sap/bc/bsp/sap/crm_ui_frame/default.htm

all worked fine.

NOW, after installing the newest available servicepacks,

I get a blank screen after using for example role MARKETINGPRO.

Same behavior with other roles,

Only if I try role IC_AGENT I get some fragments in the upper part of the screen.

I have checked all services, they are activated.

I tried to start CRM_UI_FRAME via se80, same behaviour.

Thanks and regards,

Horst
