Solved Taskbar tab shuts down Outlook instead of minimizing

[Peano]

Running Windows 7 64 Pro

I've had the Quick Launch bar on the taskbar for years. Yesterday I inadvertently killed it, so I restored it. Now I'm having a weird problem with the Outlook tab.

In this case I'm running Outlook, Pale Moon, IE, and Firefox.

Before, when I clicked one of the program tabs, this would maximize the window if it was currently minimized, or minimize it if currently maximized. All the tabs continue to work this way except Outlook. If that window is maximized and I click the tab, it shuts Outlook down and the tab disappears.

Although this isn't a major problem, it is a nuisance and also quite a puzzle. Any ideas as to why the tab might be shutting Outlook down instead of minimizing it?

When it seems to disappear, see if it's not at the notification bar (right side). If you see a yellow outlook icon, right click on it and un mark Hide When Minimized

You are my hero! Thank you so much. Puzzle solved, nuisance banished, happiness restored.
