Another UX issue. This test ESXi system has only 2 guests but as you can see the table is truncated so that you cannot see moe than one guest. This was in Chrome 44 on Windows 2008 R2.
Had this too on Chrome on OSX 10.10
Thanks for reporting this. I think I have it fixed!
Great news - had the same issue on Firefox 40 on Windows 7 SP1.
