WTF?

Okay, I'm not amused. My journal layout just changed by itself. First it was generator, and when I changed it back to Opal, my color schemes was gone. Is gone. It's blue/grey and ugly now.
Argh!
I was going to change my layout anyway, but shouldn't I be given a choice? I want my white/blue back!

Okay, smart people...

... I need your help. Again.

Everyone seems to have these nice drop-down boxes for their comments. The ones where you click on the link and a menu opens? Know what I mean?
I don't have them. I thought it was the style I had, but now I've changed it to one of the new styles, and no, still no quick-comment drop down boxes. The LJ FAQ wasn't helpful, all it said was to activate Javascript, which I have activated. Besides, I can see and use them at other people's journal, just now my own.
Help?
