Not sure if this (minor) issue with the new site has been noted.
I have a lot of seat map queries saved; when I click on the 'saved queries' a drop down appears, with a scroll bar to the right.
Any mouse action I take at the scroll bar - the drop down disappears...
Work around: (a) use keyboard arrows / page down (which breaks my work-flow), or (b) go from the 'View saved queries' page, opening new tabs for each query.
