When I open a Quark document on my Mac at home that I have created on my Mac at the office (both Quark 8.1.2) I notice that a text box has moved slightly, but not all text boxes, this could be a potential disaster if I didn't notice it. Can anyone tell me why this happens and how I can avoid it? At work the OS is 10.4.11 and at home it is OS10.6.1.
