I believe that Windows 7 may be broken in this regard, although
I have never seen the issue Alexandre mentioned. Windows seems to
sometimes put things into the permanent config when they clearly
should be non-persistent; or it fails to clear stuff out when
switching from one SSID to another. I don't know if this has been 
fixed in Windows >7, but it surely isn't a protocol issue.
