Tower view not staying in place

Hi,

I have a little problem here. When I select the tower view for an airport, it isn't staying in place like it always used to do before. When the aircraft moves, the tower viewpoint moves as well, and not a little, it moves quite a lot in fact. I think it has started to happen since I got EZdok, but I am not a 100% sure, maybe that's what causing it. Any help would be great, all I want is to make the tower view static.

Thanks.
