RDP "alternate shell" not working

Question

I've been trying to use the "alternate shell" option of RDP to start a remote program immediately after clicking in the .RDP file, but it isn't working for me: after starting the RDP session, the standard Windows shell shows up (like if the server is ignoring the "alternate shell" and "shell working directory" entries)

I'm using Win7 Professional as RDP client (MSTSC v 6.1.7600) and Win2008 Srv as server

This is my .RDP file:

screen mode id:i:1
desktopwidth:i:800

Fixed using RemoteApp. For reference, here's the .RDP file generated with the Remote App wizard:
