Make SteamVR and others work?

Anyone knows how can i make SteamVR work with Sandboxie?

When i start the games normally SteamVR detects the game (or the game detects SteamVR?).

But with Sandboxie they don't notice each other.

Same with other programs (FlawlessWidescreen). They don't see each other running.

I gussed i had to do some OpenIpcPath things ending with *\BaseNamedObjects\* *\RPC Control\* but nothing works.
