I believe this issue is specific to how you use Python/Tkinter.

I attached a sample project that shows a similar concept and writting on a label is working.

Also, one tip: when you embed a window in RoboDK I recommend you to run all RoboDK API operations in a separate thread.

Hi Albert, thanks for your reply.
In your example, the text field works, but if you resize the embed window the text label freezes and cant be writable.
