This is actually with version 4.2.0b1730. I am at work, running XP Pro SP3, on a heavily restricted system. This issue is when I open the Site Manager window. On the top of the treeview on the left, the "site list search" box overlaps and treeview and covers "My Computer" a bit. When I click and give focus to the text box, the search box positions itself properly.
I can't figure out how to attach a file to this reporting system, if it's possible, so here is a link to the screenshot:
