katie, i may have some news on this click shift issue. i switched monitors with suzanne because she claimed mine was fuzzy and she no longer needed hers. when i connect my CPU to her old monitor i get her click shift problem. Meanwhile, her CPU is cured with my old monitor. I get another monitor (from a third machine) and connect it to my CPU and i no longer have the click shift. In this office, i can begin to conclude that suzanne's old monitor was the culprit. it seems to be a long shot but i dont know that much about video/ monitor stuff to really asses these facts and draw any other conclusion.
the monitor in question is a viewsonic GS773 series. the two working ones are Viewsonics G773 and E773.
i'm going to run a couple more tests at lunch to see if this holds anymore water. as fun as this is i have to get back to work.
