Hi There Since updating to 39.0 I am having issues with my google calendar functioning correctly. The scroll bar located on the bottom left hand corner used to select visibility of different members calendars does not track correctly with the mouse. On occassions it also locks up when trying to display another members calendar. So far I have tried disabling all Add-Ons and themes and using Firefox in safe mode, unfortunately issue is still present. Picture with problem scroll bar attached... Kind Regards Guy
