When exporting a document from OOo Impress 2.0/2.0.1 to Microsoft PowerPoint
97/2000/XP, the placeholder text on the notes page has it's vertical alignment
changed from top to middle.  Attached is an empty PowerPoint document created in
Office 2000, the same document saved to Impress, then the Impress document saved
back to PowerPoint.  The original PowerPoint document and Impress document have
the same vertical positioning for the placeholder text.  Only the exported
PowerPoint document is different.

Right-clicking on the placeholder box in PowerPoint and selecting "Format Text
Box" brings up a dialog box.  Clicking the "Text Box" tab and setting "Text
anchor point" to "Top" will put reset the placeholder text alignment problem.

My guess is that when the PowerPoint document is exported, the placeholder text
alignment is set to middle left regardless of what the actual "Text anchor"
value is.  To access the "Text anchor" value, right-click on the text box in
Impress and selecing the "Text..." option to bring up a dialog box.  Click on
the "Text" tab and the "Text anchor" option will appear.  Setting the "Text
anchor" option to other positions still resulted in the text appearing in the
middle left on export to Word.
