I never heard of - at least or paid attention - to the Pages (and other new) features, so I didn't knowingly set it, and made no adjustments of that kind after installing 2. If Fences did it by default, well, that's a different story.
The excluded icon started inside a Fence, but upon discovering the two in that Fence were overlaying (the lack of snap-to), I dragged it out into the open. Same thing the second time. There are also several other icons on my desktop not in a Fence and those had disappeared too.
This morning I decided to file this as a support ticket with screenshots - #FXJ-112-20092 - and then went back to Fences Pro. In setting up its "Exclude from quick-hide" there was some odd behavior with unexcluded icons jumping around, but at least it has that feature and everything has settled down for now.
Fences needs a snap-back (or snap-to) feature desperately. It would solve a lot of problems.
P.S. In these message/replay boxes, at least with Opera, when I press Enter for a new paragraph, the spacing registers below but the cursor instead jumps to the top of the box and forces the first line to the right a couple of spaces. I've noticed it every time I've posted here.
