Unity dash autohide not working correctly

view full story

http://askubuntu.com – I don't know if this is a bug, but my Unity dash autohide function stops working sometimes. I have autohide enabled, and dash autohide works well most of the times, but now and then, the autohide stops working, and the dash is always present. I go to system settings, and confirm that autohide is enabled. I then disable the autohide, enable it again, and still autohide doesn't work. Does anyone have the same problem? Is this a known bug?
