Hi @Claus_Thogersen – thanks for the question, and sorry for the trouble here.
Unfortunately, Geoff’s description is pretty dead-on, and screen readers that depend on reading what’s rendered in standard Windows text areas are not going to work. While there may be screen readers out there that could work (by using real time OCR), we’re not aware of any yet. You can find some more details about this in this thread.
Thanks for checking, and sorry that we don’t have a better answer on this right now.
