PSE: failure-to-edit icon?

[STS]

I selected a photo in 'Organizer' (PSE 3.0.1) then clicked on 'Standard Edit'. Once in Editor, as the image was very washed out, I clicked on the 'Adjust lighting' feature in 'Enhance'. I then used 'Shadows/Highlights' and 'Brightness/Contrast' to substantially darken the image so I could better see some features.
I saved the edited image in the usual way (click on 'Close' then 3 or 4 dialogue boxes to get through) then was bounced back into Organizer as normal. However, instead of finding my edited image, there was a computer 'drawing' of a grey/black photograph, ripped diagonally from bottom left to top right! (In the 'Version set' the original and an earlier edit were displyed still, thankfully.) No writing on it; no reference in 'Help'! I even went to the Adobe site but it was worse than useless: I typed 'edit' in the search function and got, and this is hard to credit, no matches!
Anyway, does anyone know what is going on? All comments gratefully received.
Thanks, Steve

Are you sure you have not moved the file to another location or renamed it without going through organiser as that icon symbolises a file that cannot be found at the original location?

You could try File > Reconnect to see if organiser can find it automaticly.

Thanks for the suggestion, but I tried it and couldn't locate my edited photo. I went back to Editor and made sure I made fewer adjustments to the original, in case I was over-stretching something, and this time it popped up in Organizer as usual. Weird!
