Never mind. It seems that this problem was being caused because the document window somehow became unmaximized. Duh. Sorry about that. Please delete this issue if possible.

Interesting... I guess this means that your screenreader can actually read out text that's rendered onto bitmaps, but since the window was minimized, the bitmap was never drawn.
This means that you might even be able to make very limited use of the visual modular plugin screen I'm working on. Of course the usage of this screen will remain optional (I didn't forget about you :), but for sighted users it will at least give a more usable overview of their plugin setup.

It should not be able to read text rendered as bitmaps. Is the sample map really rendered as a bitmap? If that is the case then something unusual is definitely going on behind the scenes. I have never been able to view text in any other application that uses bitmapped controls or even in OpenMPT's pattern editor for that matter.

Oh and sorry for reopening, but I did not know how else I could post a response to your note.

Well, the note=>sample mapping is definitely done using GDI's (ancient) DrawText functionality, so maybe your ScreenReader can intercept these calls, but it doesn't work for more fancy drawing methods.
