I've not used AC on Windows in several years now... but back when I did... the behavior that you illustrate (a lozenge shaped thing appearing instead of the tool tip) - was a result of the Windows text size having been modified in the system settings from the standard 100% to something else - like 125%, etc.
The solution back then was to change your system appearance settings back to 100%.
[Off topic: at the time - AC was the only app that had problems at other than 100% size that any of us talked about. Since then, I've found that recent versions of QuickBooks for Windows also will not display itself properly other than at 100%.]
