On my Viewer 3, certain windows do not show any content. The window opens but nothing is in it. This is not true of "Notecards" or "Chat windows" but is true of "Profiles", "TOS, "help settings", the "Search" function, and perhaps others. This has gone on for almost a week. I have checked and installed a new "driver" since, I have re-started my computer, and no improvement. Ronald Schmid
