BI 4.1 SP2 Patch1 finally applied. Did not fix 
We also tested with laptops not on corporate domain so do not receive global policies and same thing.
So pretty sure this is a bug.
SAP transferred the 'incident' to BW-BEX.... crud
Anybody out there running BI4.1 Sp2 dashboards in netweaver portal 7.3?
