Todd., this is a phaenomenem which has nothing to do with the 
drivers. I should have mentioned this in my data sheet.
It has something to do with the grade of magnification of the 
image in PS. It seems to be a form of interference of fine 
structures (lines) during the sampling/resampling process in PS  
which appears while creating larer or smaller images. The 
raw-files of the images are the same. The interferrence came up 
by downscaling the large image. If I upscale it again, it 
disappears. You can reproduce the same phaenomenem with 
the piezo test file (lines pattern) which comes with the piezo 
software, it is visible on the monitor by stepwise magnification.
