Noticed that if you deleted a script in the “MouseEntered” event (momentary button) and pressed the apply button, the “MousEentered” remains bold blue. Same true even after you committed and saved the project. The other events ( mouseexited, and mousepressed ) are deselected when the script is deleted and the apply button is pressed. Randomly tried other buttons and it works ok. Version 7.3.3-beta2 (b543) Tired to dynamically change the border with “MouseEntered” but it didn’t work. Don’t know if this is possible or not. ---

I bet if you go into the binding there is some white space left over on the Script Editor tab. If you remove all whitespace (through Ctrl-A) the bold will go away. ---
