Web pages that are reduced to taskbar won't show when hover cursor over them
I am running the latest version of Firefox on a Windows 7 platform with Bing as my homepage. If I open several web pages and reduce them to the task bar, they will not show full screen when I hover the cursor over them. It works with pages that are opened in IE. This use to work fine but stopped working a couple days ago. Funny thing is, this very page I am writing on DOES show when I hover over the small icon in the task bar...?!
All the reduced pages show up in a row across the bottom of the screen, and as I move the cursor across them, only this support page will enlarge full screen, the rest show a full screen of white with a round circle spinning endlessly.
