How to check if you've stopped following.

[mmcookies]

Check for the "You are following blah" frame being visible. Don't know it's name, but it's the yellow text in the middle of your screen. This is the absolute most reliable way I found to handle this.

So after working on other higher priority addons, I've recently came back to this...

In response to zanthor's comment, I went and dug up some wow's ui code

The following is in ZoneText.lua

function AutoFollowStatus_OnEvent(self, event, ...)
    if ( event == "AUTOFOLLOW_BEGIN" ) then
            local arg1 = ...;
            self.unit = arg1;
            self.fadeTime = nil;
            self:SetAlpha(1.0);
            AutoFollowStatusText:SetFormattedText(AUTOFOLLOWSTART,self.unit);
            self:Show();
    end
    if ( event == "AUTOFOLLOW_END" ) then
            self.fadeTime = AUTOFOLLOW_STATUS_FADETIME;
            AutoFollowStatusText:SetFormattedText(AUTOFOLLOWSTOP,self.unit);
            self:Show();
    end
    if ( event == "PLAYER_ENTERING_WORLD" ) then
            self:Hide();
    end
end 

As you can see, the autfollow status frame is also hidden by the "PLAYER_ENTERING_WORLD" event.

Perhaps this is the implied AUTOFOLLOW_END that's causing inconsistencies?
