As another poster pointed out, full-screen mode is not the same as maximized. Full-screen mode is for projecting, and it doesn't have any window decorations, backgrounds, buttons, menus, etc. > >(b) Mike hasn't tried it in full screen mode with the Radeon driver (or if > >he's tried it with another Radeon card, then not on the same machine I > >use). > > Again, I only use applications maximized. You were quite clear > about it being maximized also. Again, not maximized. Open a document in acroread, then type <Ctrl>-L or pull down the View menu and select "Full screen". It's the fact that "full screen" means an unadorned, full-sized window with a black background that made me think they might be communicating directly with X rather than through the window manager. > >(c) I'm imagining it. > > > >So any suggestions, verification, etc., would be welcome.

We've seen confirmation in this list and/or valhalla-list that it actually happens, and (so far) only with the Radeon drivers, and in both KDE and Gnome. As a certifiable(!) non-expert on video drivers, I defer to your expertise on this point. I have posted to the Acrobat Reader support group, but I haven't seen any followups yet. I did discover that the window is moveable with <Alt>-<Button1>-<Drag>, so at least I have a workaround.
