I tried to find the problem in the forums, but didn't get it (maybe my English..).
I just updated from wp 2.0.7 to 2.1. Everything fine so far, but writing a post I cannot find how to change between wysiwyg and html, nor how to include links, bold, pictures etc, what was in the tab-bar above the post field before. Also the Logout-field nearly does't show up. I thought it's a browser problem, but seems not to be so.
I have the default theme. In the sidebar now the calendar shows up very big. What to do`I'm not a specialist...
