Ooops
Upgraded to the latest WP engine, and it broke my navigation. I’ve no idea why WP doesn’t support a decent drill-down navigation menu (then again, maybe it does, now, I’ll have to check) but I had to roll my own and now they did something in the last upgrade that broke it. I’ll have to experiment with it and see what happened.
I don’t like this version of WordPress, anyway. It seems almost Mac-browser-hostile (all of the post editing buttons have disappeared in Firefox, Opera, and Safari). Maybe I’ll have to pull up stakes and move again.
