BEx Query Designer -> Execute pops up blank Internet Explorer session

Hi gurus,

From BEx Query Designer, I choose Execute, and it pops up a blank Internet Explorer window rather than the query.  It says about:blank in the URL and the page is white.

I read some posts that say to run RSPOR_SETUP, but I don't have a Java system or Portal system so does that still apply to me?  I want the URL that pops up to point to the BW system which is an ABAP system.

E_URL_PREFIX                    http://BWSAPF00.mydomain.com:8100

E_URL_PATH                      /sap/bw/BEx

E_URL_PROTOCOL                  http

E_URL_SERVER                    BWSAPF00.mydomain.com

E_URL_PORT                      8100

E_SUBRC                         0

Warm Regards,

CM
