Hi Matthias,
thanks for the update. Adding a Delay of course sounds like something does not work properly yet, but as long as we cannot confirm it for 1.5.7 it will be diffcult for us to fix something. Still happy you can proceed with your measurements.
Something that I forgot to mention last time: Condition has a Debug mode that can be activated by right-clicking somewhere into the tab:
It was more a feature that we implemented for us to debug things, which is why it is a bit hidden, but can be used by everyone as well.
It will print out further infos to the Debug to see which data is compared, which type it has and whether it resulted in True or False.
Maybe you can see that way, whether the variable is evaluated too early or whether the parameter is not correct yet.
Let us know if 1.5.6.30 leads to an improvement.
Best, Axel
