Visual editor doesn’t work with Opera anymore

Ok, here’s the problem. I’m using WordPress 2.2 for maybe 2 weeks. Everything was working fine. But from yesterday I can’t use visual editor anymore in Opera 9.21. It loads, but no buttons are shown (screen ->). It works fine in IE7. What’s interesting, when I click “Code” then the visual image buttons shows up, and are clickable, but then I can’t edit text anymore 🙁
Please help, thx in adv.
