Problem using the forceShell command

I am trying to use the forceShell command in order to change the user shell when the user selects it from a dropdownlist. Currently i am using the following command:

?command=forceShell&shellURI=shell.shellName&returnUrl=startPage

where shellName is the name of the shell to use and return url is the page that will be displayed. When i execute the command the startpage is displayed but the shell is not changed. Does I need to do something else in order for this to function? Are there other ways to perform this action?

Francois:

The sintax seems to be ok. Try to change to another returnUrl.

Regards.
Norberto.
