GarrysMod Multiplayer Problem

It seems when I join any Multiplayer server on Gmod, I can no longer access my prop-spawn menu…
Is this a known bug? is there a fix?

Please do tell.

I am having the same problem, also with my scoreboard.

After some extensive digging I found the problem to be ASS_Mod, It conflicts with the menu whilist on a Multiplayer server
