Current ICE versions (from 2011A) have full support for other DPI settings. We recommend 96 DPI however, since that's the setting where ICE will look at its best.This is probably due to the Windows DPI display option. In this case, you might notice that the right part of the content of some dialogs is not accessible and falls of the dialog.
You have to go into your display properties of Microsoft Windows. Under the Advanced Part, you will find a DPI setting. You have to make sure this is set on the default 96 DPI, and not on 120 DPI. This is sometimes the case on some notebooks, by manufacturers which change this during installation (e.g. Dell notebooks). Some ICE dialogs might not scale properly if not set at 96 DPI.
