In the latest update,when I put in my initials for my name, the spellcheck constantly wants to change them. It never used to do this. Once I put the@, it changes the F to a G every time. Anyway to fix this w/o hiting the "x" each time?
Safari has Substitutions under the Edit menu which if you select Text Replacement, takes you to System Preferences/Language & Text/Text where you can set up a substitution. That should make it a universal replacement.
