Under previous versions of Crossover, the print on the page would often disappear while scrolling. This was particularly true when the page had an open note on it. The problem was quite annoying. Under Crossover 4.0 this behavior has vanished. It performs as well as Windows in this respect, at least.
I have not yet had time to consider other aspects of Acrobat, but I did notice that when I brought up the banner from "Help --> About Acrobat" I couldn't get rid of it.
