Hi,
Another accessibility issue for screen reader users may be the use of multiple windows. I think I can access them with my screen reader (JAWS), but some users may not know how, or they may have a different reader.
The only other issue that I can think of is more of a hassle than impediment. Screen reader users need key-presses to “see” the status bar. It can be annoying to have to key up to the bar, then key down again if you want to read the main window text. This is obviously more of an issue if the bar contains innfo that is important and continually updating, and there is no indication in the text that it has changed. And it is possible that some screen readers won’t even read the status bar.
The only solution I have come up with is to include status info as part of the room header. This may clutter the screen, but I don’t think that will matter to most screen reader users.
