Except for the 'About Reader XI' response, all windows called up in Reader are illegible.
The documents are displayed correctly, the menu bar at the top is clear, pull down sub menus are clear. But when a new pane is opened by a menu sellection (eg Help -- About Plugins, or Edit __ Preferences or Edit -- Accessiblity -- Setup Assistant) the text is invisible.
If I have made any changes (eg highlighting) closing the document prompts a (presumably) save option, which is also invisible.
This problem has survived updates (from X to XI) and Repair Adobe Installation (just now).
How can I fix this?
