OS: Linux Mint/64bit
Trying to rename a file (say,for ex, to save as an original "master" photo so I don't lose it for revising to later changes).
I tried several times, when making a slight change to a photo, or in renaming a photo to a "master" file, a dialog box appears stating: "an error occurs during rename" (see attached screen shot)...same occurs when I try "save as"
I then thought it might be a permission issue, so I went to the photo's "properties", click for "Read and write" (change from from "Read only") dialog box states "sorry, could not change the permissions of etc etc"
Actual behaviour (bug): <Current wrong behaviour of XnView>

Expected behaviour: <Expected, correct behaviour of XnView> make a change to a photo (i,e remove white dots in photo, filter out bad spots, etc, then rename or save as)
Thanks for any help
