Walt, I make a habit of rebooting my 942 and 811s twice (once soft, once hard) after receiving a software download. I don't know if it makes a difference, but I've been doing this ever since I had VOOM STBs and rarely have post download problems.
I was too busy last night to noticed if I received L2.83, however I did receive my purchased 942 yesterday afternoon. I opened the box, but I won't have time to play with it until tonight or tomorrow.
Anyway, I'm just hoping the pix problems go away for L2.83.
