Glad to hear that you were able to get to 2.01. Sorry to hear you have had problems. In my hands, the 2.01 firmware has been more touchy than the 1.60; there seem to be a small subest of us with issues.
Were you using the HTML screens to modify an Action or the Beta Flex client. Can you describe the Action as it was before you started and what changes you made and what buttons you pressed in what order. I’ll see if I can recreate here.
