Every time I open the Rock interface for PitBull (or click an item on the Rock interface) my entire WoW locks up for varying periods of time (5 seconds to "however long it takes for the server to disconnect me). This makes it near impossible to configure the addon as it takes hours to do even the simplest things, which is a shame as this is probably the best unitframe mod out there (I don't really want to use ag as I prefer a UI for all of the options, makes things quicker for the initial setup).
I am using Pitbull +53016.22. I have tried it in unpacked and packed mode, and with all of the extra modules removed and the same thing happens.
Oddly enough running the game without any other addons, configuring it, then logging out then back in with the other addons on seems to have alleviated this. There is still a short freeze on certain actions such as configuration mode, but this is to be expected and is acceptable. I would be interested in knowing why this works, if anyone has any ideas.
