Ubuntu's OpenOffice formatting changed from XP's OO formatting

[Joseph]

I used to use OO with Windows XP and formatted the odt documents as needed.

Then when I changed to Ubuntu, and bring those OO in XP documents, the 
formatting has been changed.  Changes are such as:
      Areas where font size is altered
      Page formatting (margins)
      Text style changed from Comic Sans to New Times Roman
            How can I get some more interesting fonts???  Everything 
looks the same


I have approximately (probably more than) 1000 odt documents made with 
OO in XP.  It is so time consuming to make all these changes.  Seems 
that they were made with OO in Xp the settings should be the same with 
OO in Ubuntu....

My question:   Is there a way I can set OO or Ubuntu, so that documents 
will maintain all the previous settings in which they were originally 
saved?

Thanks in advance for all helpful replies
