Status: UNCONFIRMED

(Calendar :: General, defect)

Steps to reproduce:

Create a new event by dragging a time frame inside the calendar.


Actual results:

After I released the mousebutton, sometimes the calendar gets refreshed.
This deselects the event, and I'm unable to type in my event directly.
It happens more often after I've left calendar for a while. It is reproducible when I restart Thunderbird and the first thing inside the calendar is creating an event. 
When I wait 2 minutes after Thunderbird is restarted (and a normal refresh occurs) a new event still triggers another refresh.
Creating a second event won't trigger a refresh.


Expected results:

The calendar should not refresh, or at least keep the new item selected for editing the event text.
