where is 1.7 located? The attachment on the first post is for 1.5, so I assume it is still the most current release?

also, I've checked many times and the app isn't available to download from extras-devel (for me anyway ... extras-devel enabled, searched for 'psswitcher', nothing found).

I had to download and install manually. Not a problem for me, but may be limiting take-up of the app if people can't find it where they expect it to be, so thought I'd let you know.

ps - glad you got the proximity/light thing sorted, I was just about to post a very puzzled query on the strange behaviour I was gettign in 1.4, it makes sense now :-)
