Help with HL2 SP entities

[Sami]

Here's the problem:

I have my HL2 mapping config setup with all of the important files with the HL2 SP things(NPCs, weapons, etc.) in them. Now what's going on is that under my defaut point entity it shows all of the HL2 SP things with the other entities but when it comes to placing them in the world, I can't. They don't show up on the side list. Someone please help me soon.

I'm having the same problem.
EDIT:

Ok, I found out how to switch. When you're in the Source SDK menu in Steam, theres a "Current Game" drop-down menu. Choose the game you want to map for.

Is there a way to change inside hammer? or do we gotta close it and reload each time?
