Oh noes, more bugs.
1. Mail window - no idea for now, it should not be like that. Just delete these files in the meantime:
eq2ui_mainhud_openedmail.xml
eq2ui_mainhud_mail.xml
2. Should not be like that either, the [x] should be above the scrollbar in that mode. Workaround: You can also scroll up by just grabbing the scrollbar with your mouse and pulling it up or by using your scrollwheel on your mouse, both are much faster anyway.
