This is interesting about the dpi & glitches during the beta. I have 8.05, and my monitor is 1280x1024. The sliders for the selection boxes only partially appear -- it's like the actual slider-part, just the little rectangle you click on to slide, is floating out beside the selection box. It's very hard to see.
That said, as I posted separately, I also have only weird sizes to choose from. Lots of "APLI" ones that are all A4, almost all the Avery ones are A4, and a lot of others are Japan.
I'd really like to know what's going on with all this. First, where are the standard U.S. sizes & labels, and second, are these display bugs being addressed at all?
