In most of my photo's there is a red line that runs from top to bottom on the right hand side. Every now and again it's not there but for the most part it is there. I shoot an Olympus Evolt E500. I thought maybe it was my lens which is a Zuiko Digital 40-150mm f3.5-4.5. I switched to my Zuiko 17.5-45 f3.5-5.6 and it's still there. Over this past weekend I made the same switch and it wasn't there, but today it was. Any help?
