60 Voucher icon menu hijacks game

[ElectricPotato]

I was playing on an existing character, and i saw the lvl 60 voucher icon on my menu bar, so i clicked it to see what it was.  The popup window with a confirm button, had no way I could discern to cancel out and resume normal game play.  The emote wheel could be summoned though.  I had to use taskmanager to terminate the taskprocess.  Forgot a cancel button NC?
