Focus problem

[Dresden]

First off, thx scott for all you hard work. I absolutely love nUI+ and i can't wait for the next version.

My problem is that sometimes my focus does not get set or shown. I basically use two macros, one for fear and the other for banish, since I'm a warlock. And the one for Fear works with out fail and perfectly, however the Banish does not. So i'm wondering if there is something i'm missing with in the macro, or with Banish, or does nUI handle it differently depending on the spell. Here is the Macro I use for Banish (it's the same as Fear except for the spell name):

#showtooltip
/focus [target=focus,dead][target=focus,noexists] target
/cast [target=focus,btn:1] Banish
/clearfocus [btn:2]

Basically with Fear i just have to activate the macro and it works everytime, however this Banish one will not. I have to actively set the target again, then re-activate the macro.

Any thoughts? Or is there more info that I can provide to aid?

Thanks
