There are overlapping tool tips in the admin (specifically in the configuration/shop settings). One cannot read the underlying tip as the top tip covers the text. If you will set me up as a contributor on http://dev.virtuemart.net I will assist with bug reporting.
Initially you can help by grabbing the SVN version, testing and reporting bugs on the bug board: http://forum.virtuemart.net/index.php?board=127.0
Inf on SVN: http://dev.virtuemart.net/projects/virtuemart/wiki/Setting_up_a_Development_Environment
