Hi and thanks for using the library.
What gooey version are you on? I reckon 2024.6, over Gamemaker's 2024.6.1, right?
In any case, it seems there is indeed a bug when you try to use a UI widget in the same frame as creating the gooey object automatically. Given there's been an Scribble update just today, I've gone ahead and released 2024.7, which should fix the above. Can you please try and let me know if it works?
Thanks
