I dont know why, but the column headers always appears broken when i scroll the screen, i take an image to see what im talking about
This looks indeed strange.
Which LibO and OS version are you using?
Is it a new installation and the error appears since the installation?
If the installation is older and you only observe this problem very recently, a reset of the user profile could be a solution.
For details please look at:

The Os is Windows XP Profesional SP3 version was 4.0.1
I just download the new one, 4.0.3.3 and i installed it, every thing is good for now. im going to watch if it happens again.
Thanks, 
I glad the problem is solved. Could you please click the ceck mark button that the question doesn’ t appear anymore as unanswered. Thanks
