I have gVim installed. Under Vista and XP, this offered me an addition to either the object context menu of "Edit with gVim", or an addtion to the "Open With" context menu of "gVim". This would let me send arbitrary files to gVim for editing.
Under Windows 7 64-bit, I have installed gVim -- twice, as it happens -- and there's no menu item.
How do I add an option to send arbitrary files to gVim for viewing/editing?
