I'm having this trouble, also. But I'm having it both with this account, which I'd put in for cancellation couple weeks back, then changed my mind- AND a test account I activated today. HUDs aren't working, or if they do, they work ONCE then stop. Anything scripted, yah. Across two avatars, one of which is brand new. Across Singularity, Firestorm, Alchemy, SL Official. Across Linux and Windows10. On three computers. I'm freaking stumped.
