How to change default browser to Firefox.

Hi,

I've upgraded our Solution Manager 7.0 to EHP1. Most of the applications that I use: sld, smd, user admin, etc. run fine in my default browser, Firefox.

But when I use a workcenter, RCA for example, and I open a webdynpro application which runs on a separate browser window, Internet Explorer is always used. How can I change this behaviour to choose the right default browser ?

Regards,

Joan
