QTR-Quadtone RIP

Has anyone heard of this?  I have been using QTRgui v2.4.3.23 just fine 
for a few weeks.  Suddenly, last night, I could no longer print in 
portait orientation.  I could choose portrait rotation in the GUI and 
the little thumbnail on-screen would show the image in proper portrait 
rotation.  But as soon as I click Print the image immediately rotates 
to landscape mode and that's how it prints on paper.

After many attempts and computer reboots (it even did the same thing in 
calibration mode) I gave up.  I resorted to uninstalling the entire 
thing, running QTRCleanOut, and re-installing.  It now prints properly.

Anyone seen this before?
