Hi! I am trying to copy and paste some learned ir codes from a TSU7000 file to a TSU3000 file. I opened both files in their respective programs, went to the button with the learned ir code in PPENG, highlighted and copied the code data, then tried to paste it into a newly created button in PENG, but it's not working. In PENG, I edit the properties for the button, hit "Add Ir Code", pick "Custom Ir code", and give it a name, but the edit box where the code is supposed to go stays un-editable. I can't even type into it. I am using version 1.1.3 of PPENG, and version 2.1.1 of PENG. What am I doing wrong?
