Yes. I had that problem too but I had not noticed it as I use Chrome. It may have something to do with and Absolute/Relative setting in the code. There was a fix I saw some time ago, so have forgotten but it is covered in a thread. It as very easy but I hate coding (why I like Xara), just had to add an IF in the code. One of the code monkeys should be able to help you here.
The drop down menus did display but at random points, sometimes way off the screen.
Sorry its vague but hth

Chrome is taking off big time.
