text substitution stopped working
Text substitution (Sys Prefs > Language & Text > Text) was working fine for me since Lion came out but it has now stopped working, in Mail anyway. No amount of turning it off, then on again, rebooting, resetting, etc seems to fix the problem. Auto-correct as I type is still turned on in Mail prefs, as it always has been. Adding a new text sub string doesn't work either - it simply seems to have become disabled.
Any ideas?
