Why thank you for that kind suggestion, kiddo. But really, a little care towards not further degrading the signal-to-noise ratio of the cybersphere isn't too much to ask, eh? Along those lines... I found I was able to successfully save the file as a png. I then opened the png file in GIMP, and saved the tiff.

Thanks but...you might work on your reading comprehension.

This may be related to the other thread about an unspecified error while saving tiff after upgrading to XP SP3, but I'm running SP2. 1 gig of memory... I loaded a USGS topo map, a large tiff file as can be obtained from libremap.org. Made some edits, then tried to save, as a tiff. Got "unspecified error". Same thing with jpeg. Can save as gif or bmp, but whites get inverted to blacks in that case. Saving as a pdn and reloading is fine. Finally tried select-all and copy, in hopes of getting my edited image out somehow. Seemed to go into the clipboard ok (took a while), but on exiting and starting Windows Paint and "paste", got "error accessing clipboard data". The file really isn't that big, 7.5MB...the original tiff and the pdn are about the same size.
