Thanks for the info, Howard. I'm sure it'll come in handy, only I've fixed it. The positioning of the elements, over the bg image in this design is very unforgiving (1px tolerance) and I had used a percentage background position. Converting to pixels seems to fix the problem.
Thanks for looking and sorry if I wasted anyone's time. It might be handy if this thread is kept open, as you never know what could crop up next, with IE!
Definition: Computer rage is a heightened physiological response with associated feelings of anger and frustration resulting from using a computer or other complex electronic device. It may result in the physical assault of the computer or similar item. Computer use often leads to verbal abuse and occasionally physical violence towards the object. Computer rage may be caused by distress due to a hardware or software problem which the enraged person is unable to correct.
