Zoning locks up with Fetish sometimes...

[skyrocket]

I looked for this and did not find anything. For the Past 4 nights this has happened atleast once everynite. I am using Nightfall Fetish program. When I zone during raiding from place to place my screen goes thru everthing and then says "adding character to zone" then says "loading UI interface" and my screens stayes black with that loading ui interface up, but nothing happens. I can hear my other raid members in the zone and all i can do is click the exit button that is up which takes me to windows screen. Is there anything i can do so this doesnt happen? I get worried everytime i zone with this fetish program now.

thanks
