This bug was tested LibreOffice v4.1 RC1 running in windows 7 and XP. It appears that LibreOffice loses formatting when importing MS .docx files. I have attached an example.
Steps to reproduce the bug:
1. Open attached Demo-Hayden-Management.docx document in writer
2. Open attached Demo-Hayden-Management.docx document in Word2007/Office 365
3. Compare the documents.
Note from item #4 from the screenshot that the Chart is missing.
