Thanks for the reply, but I don't want my "fences" to stay unrolled & that is what that checkmark does.
I want my fences to stay rolled up until I double click them & never unroll until I DBL-click (they unroll on hover now).
I also want that "fence" to stay open until I double click again to close that particular fence (window / folder).
I hope that made sense - the hover roll out is annoying & interferes with using my other fences.
This is really like creating a folder on my desktop & adding shortcuts... which I might end up doing.
