I've been using WP 2.2 for a few months without difficulty and just the other day the visual editing toolbar on the posts and pages disappeared.
It's not a browser issue since I run about 10 other WP blogs all running 2.2 (maybe one 2.3) and they all display the visual editor in both posts and pages just fine.
Searched and didn't find anything other than browser issues here in the forum.
Does anyone have any suggestions? Reinstall, upgrade to 2.3? Thanks very much!
