Can't close a floating toolbar

Hello All,
I want a toolbar in my ActiveX control. So I created a frame window and called LoadToolbar to load a toolbar. Everything works fine except that I can't close this toolbar. If I undock and press Close button it wont close. After that if I click on the title har the toolbar becomes a small button( only close button in the title bar). In short I can't hide a toolbar using mouse. It is working fine if i call CToolbar::ShowWindow(SW_HIDE).

Thanks
Sunil
