Not a bug (0.35.2) Pressing 'Q' to exit the PokéGEAR menu does not work.

Really, the title says it all.
Unless there is a different key to exit, then again not even 'Esc' works.

Edit: And yes, this is the vanilla Pokémon 3D.

You can press 'E' to exit the PokeGear!

Ah!
Thank you so much, sir!
Now I can do my let's play episode!

 

[Goldn]

Haha, no problem!
