XnView Software

Sorry, my response is rather confusing. Try this instead...

<pre>
action screen shows image on disc image update status
open image original image original image clean
change
(flip horiz) flipped image original image dirty
save flipped image flipped image clean
undo <b> original image flipped image ...

Thanks for the quick response.

In respect of the subject of the request, after you make a change (eg flip horiz) and save the change, the saved images reflect the change. Now undo, which displays the original image, which is no longer the same as the saved image, therefore XnView should detect that ...

Open any image.
Make a change (eg flip Horiz)
Save
Undo
Close - no prompt to save changed file

This is my first post. Would be surprised if this hasn't been raised before, but have not found anything after quite a bit of searching.

Excellent product, but would really like a redo!
