i am using links 2.01 (i think - it's the flat file version) and am having problems with the span pages function.

i have searched the forum and tried the fixes, but nothing seems to work.
in links.cfg i have

$build_span_pages = 1;
# Number of links per page.
$build_links_per_page = 10;


but when i build my category pages (i haven't started entering links yet) all sub-categories show on the page - e.g. if there are 20 sub-cats there will be 20 displayed on the page.

the template has the appropriate next/previous code, but since all sub's are being displayed the next/prev code isn't being displayed anyway.
have there been any definate answers posted to this? i couldn't find them if they were.

by the way, is there a way to set the number of columns to display categories?
instead of 2 i would like to have 4


thanks for the help
