Guys
I am having trouble and, not being too technically literate, can only explain what appears to be happening. I am using a lap top running Windows 7 and the Beta version of Paint.Net. I open a JPG file and do some editing (basically removal of some white background) which all seems fine. Then I save the file, using "save", get confirmation that the file is being saved but then find that the file is exactly the same as before. I have checked that it is not "read only". I have tried saving the file as TIFF and that saves the edits. What might this be
I have subsequently found that it saves some things e.g. I added text, but does not save a deletion (to give transparency).
