I have been using DNG Converter 7.2 for some time (running under Windows 8).
Today when I start the program all the buttons and fields are non-functional and appear "transparent" in that they display whatever was behind the DNG Converter window on my desktop when it started up:
Things I have tried:
Waiting to see if it eventually woke up
Closing and restarting program
Downloading and installing 7.3
The only other software I have installed recently is Python for Windows and Scratch for Windows.
Can anyone suggest what the issue is and how I can fix it?
