UI Increases time to zone?

[acidm0on]

Ever since I installed the 3/4 Hotbars Mod (the only mod i have installed) when I zone it takes forever. Everything loads like normal, then when it gets to the part where it loads the custom UI it just takes a really long time. Before I installed the mod i zoned in a very short reasonable time. Does it do this for everyone or do I maybe have something installed wrong?

Thanks~
