Error message when trying to set repeating rows/columns on printouts:
---------------------------------------------------------------------
Bug in Novell version: You may get the error message "Invalid sheet reference" 
when trying to setup repeat rows. If you do, try this: From the menu, 
Select Tools -> Options. 
In the tree click on "OpenOffice.org Calc" -> Formula. 
Click on Formula Syntax and explicitly select "Calc A1", 
even if it is already selected. Click OK.
