Windows GUI Meterpreter Payload Question

[d4rkcon at gmail.com (Dark Con)]

I know there's a simple answer to this question but I couldn't find it 
searching around so I'm hoping somebody on the list will know.

I'm using the Metasploit GUI on a Windows box to exploit a system with 
the Meterpreter payload. Exploit works great, I get a new session in the 
Sessions pane, double-clicking on the session gives me a terminal on the 
remote machine, everything works. But the shell that I get dropped into 
when I double-click the session isn't a meterpreter shell, it's just a 
regular shell. I used the meterpreter payload (right-clicking the 
session allows me to view and migrate processes, browse files, etc.) 
just don't get the meterpreter shell the way I do when using msfconsole.

I'm trying to play around with the meterpreter scripts (killav, 
browserenum), is there a different (or any) way to access these from the 
GUI? Is there another step to take to get to the actual meterpreter 
shell from the standard shell that I missed?

Thanks for your help,
