Hi Alex,
sorry for the long delay.
I assume that scripting is enabled in general for your GUI (Otherwise the scripts would not have run even in the standalone GUI). But to exclude that cause, can you check that again in the embedded GUI?
We tried some scripts locally and did not run in to the described problem.
What GUI version are you working with? I can check if there have been relevant changes in the recent past.
Thanks and again sorry for the delay,
Eckart
