Hi, as an system administrator I'm really bugged by this, because I had to run around for this bug soo 
many times to day, so please forgive me for raising the priority ;-)

Reproduction steps:
1. Open a calc document
2. Click and and minimally drag the mouse (a clumsy click which happens ever 5th time)

Expected Result:
The tab is selected

Actual result:
You have a second copy of that Tab.


These are two bugs:
1st The Drag and Drop is not responding like normal MacOS Drag & Drop. It should only react after a 
miniature time out and a horizontal movement.
2nd The normal Drag of anything is just a movement not the copy. This means any accidental drag 
within the width of this ta and the half of the neighbour would not result in any creative action.

Aside from that:
Congrats to the first real OpenOffice Aqua release!
