Tool tips balloon displayed behind current window

rather than on top of the current window.

This also happens when hovering over controls/buttons displayed by websites.

Doesn’t happen if I use a different browser.

See attached screenshot. If I hover over a control/button that is located further away from the right-hand edge of the window, it will only display for a small fraction of a second on top of the window, before it then disappears behind the window.

Once in a while the tooltip will work properly, I’m not sure of the sequence but I think you have to click out to another window then back.

(hmm… the screenshot didn’t attach, I’ll try again here…)

Anyone else have this problem?

Maybe it’ll go away when I upgrade from Windows 7 to 10…
