Recently, when I was playing around with new hotkey settings for Diablo 3, I bound several keys to new functions, inkluding the space key. I then found out, that because of the new space key function, I could no longer skip dialogs with space, so I unbound the space key (like described in this Arqade question).
Unfortunately, the skip function still didn't work. I tried binding space to other functions and then unbind space, but it still didn't work.
How do I get the skip dialog functionality of the space key back?
