[RndTbl] trouble with Firewatir

Tue Apr 20 14:28:39 CDT 2010

I used a web page reference - consisting of variables enbedded in a  
URL - to "goto" the frame directly.  I can fill the login fields and  
click the button, but then I'm sent to another web page which is  
completely blank.

I may have to skip the login altogether, and do it manually.   
Hopefully I can still navigate within the web site.

It wouldn't surprise me if the difficulty getting in is intentional -  
to discourage robots from guessing names and passwords.  But I had no  
trouble automating my access to a different financial institution's  
site.
