Problem with "browse with xnview"

[munin]

If i click to browse with xnview in a folder, i get a warning screen saying the file doesnt have an associated program...
And when i try to disable the option Add "browse with xnview" in tools, it just doesnt. Whenever i enter the options again its reenabled.
I tried disabling it with admin rights but its the same thing.

Is tehre another way to remove the context menu entry?

My windows is 64 bits if that helps.

Do you execute XnView with admin rights (context menu on icon)?

Argh, that just had me too. Silly Windows 7... Sorted now, cheers!
