I didn't try PaintShopPro but had a look into the tiffdemo.tif .
It is formally ok - i.e. it conforms to the TIFF V6 spec, but I found
the colormap has unusual values: they all are of the form
xx00 in hex, where xx is from 00 hex to ff hex.
both Photoshop and Acrobat (exchange 3.0x) can open this image and 
display it correctly; saving the image from Photoshop results in
colormap values of the form xxyy hex where xx and yy are both the same
bytes.
