Radio button issue

Hi, having issues with radio buttons. the projects open with them all checked, but they are not active. They can be unchecked but that is all?

Sorry for the late reply.
Did you solve your problem?
I haven’t been able to reproduce this.
First question, did you use the develop or the main branch?
Cheers

N.B. I just pushed a new version to the main branch 1.3.8
The SignalGenerator example uses the new RadioButton manager and I just checked it worked here…
