StrictNodes or StrictExitNodes?

[Matthew]

 I think I am correct to say that StrictExitNodes has been negated in 
favour of StrictNodes.

However, when I use StrictExitNodes 1 I have no problems.
When I use StrictNodes 1 and have viable ExitNodes then Vidalia gives the 
error: "Vidalia detected that the Tor software exited unexpectedly."

I am using 0.2.1.26 on Ubuntu 10.04.

Thanks.
