WPF RibbonWindow and Auto-hide taskbar -->Taskbar never pop up again

in my WPF application i have an usercontrol which inherits from RibbonWindow. If this application is maximized and 开发者_运维问答my windows taskbar is set to Auto-hide, the taskbar never get in foreground, if the mouse is over the taskbar area.

Seems to be a known problem: http://connect.microsoft.com/VisualStudio/feedback/details/634858/microsoft-wpf-ribbonwindow-disables-taskbar-when-taskbar-is-set-to-autohide

Is there any workaround or solution for this problem?

Thx, jana
