Firefox Tool Tips are listed as Windows

[clijsters]

These Tool Tips appear every time a user hovers objects in Mozilla Firefox with additional information, e.g.:

• Favorites
• Hyperlinks
• Title Bar (Tab Control)
• And so on...

Every time this happens, AppBar.OpenWindows refreshes it's content.

A very very special case:
If the user minimizes the above mentioned window by clicking the AppBarIcon of which hWnd points to the tooltip, it stays minimized.
Forever.
If he hover it again, it appears in OpenWindows, but stays invisible.

Apparently, Firefox has multiple Popup Window Classes. Minimize an Address Bar Tool Tip, the Hyperlink hovering Tool Tips stay visible. (and vice versa)

This Guy had the same problem, but the only suggestion in the comments is GetWindowLong(GWL_HWNDPARENT). It's already implemented and used to obtain WindowState Information.
