Thank you for your reply.
I had not run DXDiag and as far as I could tell, there were no
errors.
I am using Quadro FX1500, upgraded to the latest driver when it became
available, and I did change the acceleration from full to one or two
increments, but it seemed that I did not lower the acceleration level
enough
This time I lowered the level even below the half point,
but there are still many files that do not show images...
Yet, I am still not clear why this problem started happening. There
had been no problems more than a year...
