Anyone have any idea how I can get the snip tool to SAVE again? It snips the

Some ideas there, like mending the registry entry for the special folder
or [re]creating the special folder, or reinstalling the Snip Tool.
Although the thread is about the Snip Tool stop saving on Windows 7,
it's likely the cures (if they work) also apply on Windows Vista.
