Pagination extension 
(http://extensions.services.openoffice.org/project/pagination) uses a StarBasic 
macro to alter document page styles. It assigns page style names using English 
names. When using the option 'Do not number first page' in that extension, it 
assigns 'First Page' style to the first page. If I save this document in Office 
97 file format, style of first page is reseted to 'Default' and I loose page 
numbers.

Steps to reproduce:
1- install pagination extension
2- create a new Writer document
3- choose: insert > page number
4- check 'Do not number first page'
5- write enough text into the document to reach page 2
6- save the document in Office 97 format
7- close it and open it again
8- page numbers are gone.

If at step 5 I insert a page break to reach page 2, I don't see the bug.
If I simply create a document and assign 'First page' style to it, I don't see 
the bug. So I think this is related to the way the basic macro do it.
