So if I am reading this response correctly you are saying I shouldn't be having a problem?
I adjusted the browser to what you used in the example:
XnView v1.96.1 (Tools » Options » Browser » Thumbnails » Appearance » [×] Use high quality, 120×120px)
Even after doing that not all my thumbnails appear - here is an example of what I see
As you can see some have pictures and others are merely colors. The colors represent the bottom layer of the psp saved document.
They have all been saved in PSP format to be compatible with version 7 and up. The info you supplied from "The Tech Guy" seemed to think the solution was using only version 12 and that is the only version I have on this computer. I find that if I change the ones that do not appear to be compatible with version X2 only, the image shows up in the browser. So if the solution is to change every PSP saved image as compatible with version X2 only, why do so many of the images show that were saved as compatible with version 7 and up?
Okay here's another swing on it. As luck would have it, yesterday I bought a new desktop computer for my husband. The OS is Vista 32bit - I opened the same tube file and all the thumbnails appear. So that says to me it's a 64 bit issue. If the intended fix for that is the 64 bit shell extension I have already installed that.
What are your thoughts??????? My thought is to scream. lol
