There is a known issue with the pop up messages that appear when say you delete a file or whatever it is – you will hear the pop up prompt type message only once. You will be able to use your tab key to hear the Yes or No buttons but insert+b will not re-read the prompt message you receive if you use JAWS 16 with Replay Media Catcher 6. I do not know why. NVDA does not show this issue with the prompt pop up messages and insert+b works. Once you know what its saying you know what to do. You can do most things like delete within Windows Explorer. Try JAWS OCR feature on these pop up prompt type messages if needed.
