Slight lag with nUI for PTR
 

First, Thank you for you speedy release of nUI for the PTR.
I installed the new nUI for the PTR & I am experiencing a very slight lag issue. When I hit a hot key to attack a NPC there is a longer then usual lag between the key being pressed and released & the action occuring on all characters (ie. a Druid and a Death Knight.) I play like characters on a live realm and do not have this issue.

I strongly suspect this is related to the test status of the PTR itself... there are no code differences with regard to spell actions between the live and PTR versions of nUI.

Is this on the PVP or PVE test realm? (I only test on the PVE realm)
