@Georg:
May I ask you to read  hints on <http://wiki.documentfoundation.org/BugReport> carefully?
Then please:
- Write a meaningful Summary
- Attach a sample document (not only screenshot)
- Attach screenshots with comments if you believe that that might explain the 
  problem better than a text comment
- Contribute a step by step instruction containing every key press and every 
  mouse click how to reproduce your problem (and if possible how to created a 
  sample document from the scratch)
- add information 
  -- what exactly is unexpected
  -- and why do you believe it's unexpected (cite Help or Documentation!)
  -- concerning your PC (especially: video card)
  -- concerning your OS (Version, Distribution, Language)
  -- concerning your LibO version and localization (UI language)
  –- Libo settings that might be related to your problems 
     (video hardware acceleration ...)
  -- how you launch LibO and how you opened the sample document
  –- If you can contribute an OOo Issue that might be useful
  -- everything else crossing your mind after you read a.m. URL

May be you can test <http://wiki.documentfoundation.org/BugReport_Details> for submitting bug reports?

Please file Bug reports with status UNCONFIRMED if your are not absolutely sure that you contributed all required background information, that the problem will be reproducible with information you can provide or that your enhancement request will be accepted! Thank you!

NOT Reproducible with a simple test document created with OOo 3.3 and "LibreOffice 3.4.3 RC2 - WIN7 Home Premium (64bit) German UI [OOO340m1 (Build:302)]" 

Closing Bug due to reporter's inactivity as INVALID.

@reporter:
