toggle2nist hangs when pressing an other button at the same time was created by juergen-home
I have this gamepad.hal as an example for my problem.
This is used with the button of a gamepad.I start a program by a button, then I can pause/resume it by another button.The third button is to stop the program.
The problem I have: If the program is started and I press pause/resume and stop at the same time, sometimes the toggle2nist_on get stucked in on state and the pause/resume will not work until I quit linuxcnc and start again. Is this a known behavior, or is something wrong in my gamepad.hal

To illustrate my issue with toggle2nist a bit more I have made a simple hal file.
The hal file makes no other sens as to show problem easily for testing yourself.
1. If I comment in
net net-mist-off => halui.program.stop
Linux runs as I expect. I can toggle the nist2 in halshow with set and clear.
If mist is switched off, a running program stops. I can start again and so on.
1. If I comment in
net net-mist-on => halui.program.stop
I can toggle the nist2 in halshow with set and clear only once.
If mist is switched on, a running program stops and the tog2nist.on LED is yellow all the time.
Is this working as expected?
