custom toolbar on windows 7 taskbar getting disappearing

custom toolbar on windows 7 task bar getting disappeared.

When I am navigating through the menu, it suddenly vanishes. I will have to point to the menu again to navigate, its been annoying. Any fix for the issue ?

Attached screen shot.

A not too well toolbar problem exists. The third party extensions and toolbars are stripped when you launch from the taskbar. Pinned sites on the taskbar are not the same as the url that you try to pin. But if you drag the site to the taskbar while holding down the shift key it will be put there as a url and the third party extensions will be intact.

These are local folders on my computer.
