I have this page that does some funky database stuff that takes a couple seconds to process, and in the meantime I\'d like to set a \"wait\" cursor so the user
Any elements that don't inherit the cursor by default (such as buttons) will need to set the cursor to inherit:
someButton.style.cursor = 'inherit';
To go back to the default for an element (and not break things like :hover with a forced cursor), set it to an empty string:
document.body.style.cursor = '';
