Not saying you are an idiot, I get daily 4-5 messages or question why the script isn't working.
I guess you are calling them idiots by this post ... since they didn't knew about the fixed screenmode.
Tested all courses and everything runs fine on all 4 of my accounts ...
+ 100+ users are hacing no issues running the script.
Might want to start looking if something worng at your end.
Try restarting the client,
If you still have this issue, fill int he "bug report" template in the first post.
After that I got the right info and I can adress the issue right away, this way I can help you out very quickly.
EDIT:
Atm there is a minor issue with the camera movements in the client, could be the issue for you.
Will investigate this further!
