My workflow involves editing images in external applications (not just PS, but others as well). However since upgrading to LR4, I have noticed that images edited in external applications then saved do not get updated in LR.
Is there a way I can force refresh of the image? I know my edits have saved correctly, as when I open the edited file in Photoshop, my edits from another external application are there. However, when I make further edits in PS then save, the image in LR still doesn't update.
I've tried discarding 1:1 previews and rebuilding both 1:1 and standard sized previews, but this doesn't do it.
