Hi Ch Raz!
Thank you very much for giving me such a good description of the bug your were experiencing with Joystick 'n Sliders. I have fixed the issue as well as the image generating error you had experienced. You would just need to re-download the product and overwrite both the .jsxbin file and the assets folder in your SciptUI Panels folder. Please let me know if this works for you. It is now version 1.0.1
