Hello! I cannot survive without this extension! However, I have been having formatting issue with the calendar view on my end. Once I turn on the extension and click myCalendar, the calendar on screen is distorted and all squished to the left. Using the alt function to call the calendar also does not return any of the courses in my coursebin. I believe USC just updated the webreg system which is why it's causing issue. If you'd fix it it would be great! Thanks again for making this extension! P.S. I have tried deleting and reinstalling the extension, which did not solve the problem.
