we've got some pretty annoying flickering in our menus which is preventing users from being able to select different views - i.e. week, month etc
I've recorded a video to show the problem - http://www.youtube.com/watch?v=OVj38H2uWXU
Could anyone shed some light on why it's happening or how i can debug it in firefox/firebug
The same thing is happening on FF Safari and Chrome.
