I just tried it and it works just fine.
I thought maybe that you might have to set StaysOpen (on the Popup) to true so that you can mouse over it (without it collapsing) ... but you don't even have to do that. Snoop works on Popups both for StaysOpen = false and StaysOpen = true (the Popup doesn't
collapse unless you mouse down somewhere).
Note that Popup(s) aren't part of the same visual tree ... from where they are popping up ... and that you must use the ctrl-shift mouse trick over the Popup ... before Snoop will refresh the tree view and load the visual tree for the Popup.
Maybe you are unaware of the ctrl-shift, mouse trick? If you hold down the ctrl and shift keys and then mouse over the visuals in a WPF application, Snoop will find the element in the tree view that the mouse is over.
Hope that helps.
