A simple tool that presses that "Skip Intro" button for you automatically within your Amazon Prime Video window since Amazon has yet to add a shortcut key for it (can you believe that?!).
Just skimming your code, looks like you never set skippedFlag to False, so essentially you’re raising and catching an undefined variable exception once per second instead of simply returning False.
If you have added SkipNinja to your Windows Startup folder, then deleting it will fix the issue. Sorry about that!
You may still run SkipNinja manually at every start-up. This issue occurs due to Windows loading up all start-up programs while on the login screen itself, even before you actually log in; so SkipNinja keeps running in the background even before it is technically allowed to, causing some sort of a "borke" — for the lack of a better technical term.
