Can't reproduce this; in all cases I see the search box, even after clearing the cache before going to the URL.

That's strange. I've seen this issue on 2.0.0.3 on Windows as well as on Linux on several machines. Firefox/1.5.0.10 shows the same issue. I also had this problem with a clean intall without any extensions or custom configuration.
Are there any ideas what might trigger such behaviour? I tried Firebug but it's useless in that case, because as soon as I open it, the page is rerendered and displays correctly.

I figured the problem out to be the banner lacking a height attribute. Therefore the menu was rendered while the banner had the dimension 0 but wasn't rerendered after the banner was loaded.

That sounds somewhat like expected behavior, but I'm not entirely sure. Do you see this problem on the trunk?

The issue seems to be fixed in the trunk.

Changing resolution to WORKSFORME since we don't know what code change, if any, fixed this.
