Gamemode Scripting: Context menu won't open!

[KO #1]

I've been trying to create my first gamemode recently in GMOD. I haven't encountered many errors (yet), but I have no idea about this one.

[B]Plain and simple, the context menu will not open[/B]

Here is the code so far:

init.lua:

AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )

include( "shared.lua" )

function GM:PlayerLoadout(ply)
   ply:Give('weapon_crowbar')
   ply:Give('weapon_pistol')
   ply:Give('weapon_357')
   ply:Give('weapon_smg1')
   ply:Give('weapon_shotgun')
   ply:Give('weapon_frag')
   ply:Give('weapon_physcannon')
   ply:Give('weapon_crossbow')
   ply:GiveAmmo( 50, 'pistol', false )
   ply:GiveAmmo( 12, '357', false )
   ply:GiveAmmo( 75, 'SMG1', false )
   ply:GiveAmmo( 20, 'Buckshot', false )
   ply:GiveAmmo( 4, 'Grenade', false )
   ply:GiveAmmo( 12, 'XBowBolt', false )
end

function GM:PlayerSetModel( ply )
	ply:SetModel("models/player/group01/male_07.mdl")
end

cl_init.lua

include ("shared.lua")
function GM:ContextMenuOpen()
	return true
end

shared.lua:

GM.Name = "######"
GM.Author = "KO #1"
GM.Email = "N/A"
GM.Website = "N/A"

function GM:Initialize()
	-- Do stuff
end

In game, the context menu just won't open. The key is binded properly, there are no errors, it just doesn't work.

Context menu is a Sandbox feature, not a base feature. Same goes for the Q menu.
Either derive your gamemode from sandbox, or copy / mimic it yourself.

Okay, I'll do that when I get home.
