Since Canvas works in a web browser, many issues (slow? button not working? etc.) can be resolved by looking at the web browser software being used:

1. If you are using Safari, please try another (Firefox or Chrome)
2. Clear browser history/cache (instructions for: Mac | PC )
3. Type in the direct link to Canvas in your web browser: webcms3.colostate.edu/canvas
4. Close your browser entirely and try the direct link again.
5. Restart your computer
6. Try another computer
