Why do I sometimes see an hourglass in Zimbra?
If you are connected on a slower Internet connection (wireless, your network at home, etc.) you may see delays when using Zimbra. Check to see if you are having slowness in other pages as well. I cannot find the Spell Check button. Safari and Chrome do not display the Spell Check button as an option. Both browsers have a built in spell-check feature that will identify misspelled words as you type; however, if you prefer to use the spell check option, you may use Firefox.
