If you press the space bar while typing in the quest name, ZC thinks you're pressing enter.
Granted, most folks click their quests, but this is noteable.
This could also be related to my keyboard.. Not really sure.
179 - Space bar in quest selection screen
Is your spacebar set as a button (A, B, select, or start)? Just tried the spacebar here and it works fine.
I'll try it on another computer. It's just the one screen though.
If I press space there, it thinks I'm hitting enter.
