NSWorkspace question

[Karsten Fuhrmann]

Hello, i wonder how can i tell the GWorkspace program which browser to 
use when a program sends the message
[[NSWorkspace sharedWorkspace] openURL:myurl]

The same code works perfect under MacOS X

At the moment nothing happens, no error or warnig.

Is GWorkspace realy required to handle such message or how is it done 
in GnuStep?
