Context Menu (Right Click) not OK with Vista x64

[ExNihilo]

Hi,

Using FC 2008.06a on Vista Business x64 bits.

With FC on a WinXP machine, right click on a file show the same context menu than Windows Explorer. In particular, the context menu placed by 3rd party programs like "7 Zip", "Edit with Notepad ++", etc.

The same FC 2008.06a installed on Vista Business x64, all the 3rd party context menu items are no longer displayed. However, they are displayed OK if the right click is made in Window Explorer.

Is it a x64 bits issue?

Thanks in advance for any help.
