Thanks Mike.
I omitted to point out that the same set of TIFFs did not cause any thumbnail nor display problems on QIU v2011, running on Windows XP 32bit.
On the Win XP Pro PC changing the Thumbnail build to single core made no difference.
I have since found out that even some of the large TIFF panoramas that have correctly generated thumbnails can not be displayed using SPACE nor double-click. Get a red "Image Read Error" on the screen.

What are the pixel dimensions of these files? I also need an answer to what I asked you earlier: when you hold the shift key while selecting Help, Analyze Current Settings, what numbers do you get for memory? You might have been right on the edge of what could be loaded before and now, your machine has slightly less available memory just due to what is currently loaded in Windows. Which brings me to my final question: when was the last time you rebooted the machine? Could be some other issues causing low memory that may go away with a reboot. XP wasn't very good at managing memory which is why complaints about loading large images are pretty much confined to the obsolete OS's: XP, 2000, NT.

Reboot didn't resolve it.
Please also note the revision to the post of mine you quoted. Even if thumbnails are generated correctly the panoramas can not be displayed using the SPACE bar.
Yes, seems like an Win XP centric problem but why is it occurring now?
That said, my XP Pro version is only a backup.
