Visual Builder not responding to create Datasource file

Hello there,

I am using Firefox version 26 along with SmartClient Version: v10.0p_2015-01-23/PowerEdition Deployment (built 2015-01-23).
I am trying to tell Visual Builder to create a datasource file from my existing SQL Table. But when I select that option and clcik on the next button on the visual builder's DataSource wizard nothing happens. But when I select the option New SQl Table and click on the next button it goes to the next screen. What am I missing or is it a bug in version SGWT 5. I recently upgraded my version from 3. Please help.

cheers
Zolf
