[ALUG] Why has 'ls -a' started mixing hidden files with the others?

When I issue an 'ls -a' or an 'ls -al' I expect all the hidden files (those with a . prefix) to appear before the others but my latest upgrade seems to have stopped this happening. I much prefer to see the hidden files separately, can I get the old sort order back somehow? I've unset all the LS options in my environment and ls isn't aliased. -- Chris Green (chris@areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."
