Photoshop Elements 4.0 corrupting TIF FIles

In Photoshop Elements 4.0, if I try to open any one of a group of TIF
files in edit mode, it gives me the message, "Could not complete your
request because an unexpected end-of-file was encountered".

Then, a file that was several hundred kilobytes gets truncated to a
size of 1K or 4K!!! Opening in another editor shows just vertical grey
bars. I never told Elements to save the file - the simple act of trying
to send the file to the editor causes complete loss of these images.

This happens whether I use "Quick Fix" or "Standard Edit". JPEG's work
just fine. I can open these TIFs in another editor and save as JPEG's
and then edit in Photoshop, so it doesn't seem like there is anything
fundamentally wrong with the TIF's. They even originally rendered
correctly as thumbnails when the directory was imported into Elements.

It doesn't seem hardware (disk) related since I can edit other image
types no problem.

Try opening the TIFF in IrfanView and saving it again as a TIFF. IrfanView
seems quite tolerant of errors in files.

But... those TIFFs aren't those strange little files that come off some
cameras along with the real TIFFs, are they?
