I have to reload to resubmit

When I first load something or I submit an answer and it doesn’t accept than the submit button gets stuck with a gear and i have to reload the page to press the submit button again.
Is anyone else having this problem? it’s really annoying especially when i’m just trying to touch up on what I know (Coming back after 2 years or so)
