We recently upgraded to 18.104.22.168.
Since then we've had several customers complain that they are unable to drag open a new appointment. They can double click or use the keyboard shortcut to open the new appointment dialog, but dragging open a time block does nothing.
The people this affects can replicate the problem on multiple computers. Possibly it may only affect Firefox....but I haven't confirmed that yet.
The user can login, show the problem, and on the same computer/browser logout and have someone new login and it works just fine for the new person.
Firebug and using the /?dev=1 feature did not seem to present me with any good error messages.
Any thoughts? Other people seeing this behavior?
