Hi. I seem to have messed up my mouse settings somehow. When I click on the bottom or top of the scroll bar (eg while in answerbank) each question moves up or down, one question at a time till it eventually reaches the end. Simillarily, if I put the mouse pointer on a question and roll the scroll wheel, the questions move a frame or two at a time, slowly, like the horizontal hold on a TV. I tried a different mouse, but the results were just the same. I have just had a new hard drive fitted, so I suppose a windows restore is not an option! Thanks for looking.
