Yes, the grey margins appear. Another strange thing if you run example x08: The first page is blank and the other pages show up. BUT if you press Enter twice fast or the right mouse button the following page shows up quickly and then again a blank screen. > If so, I may change part of the Qt > driver to make it closer to the one we use in QSAS (which works).

You could send me patches which I could try to apply and test. Or you can even tell me what I should try to change to get results. I just have no time to read the qt documentation to find my way through the code and debug.
