Databases Cra****ng - Any Ideas?

My computer is dual boot Vista and XP.  I have Access 2003 and 2007
installed on both partitions.  The problem that I am having is that
some of my Access 2003 databases crash when I try to do a compact and
repair or create an .mde when using Access 2003 under Vista.  I get
the classic "Microsoft Access has stopped working" dialogue.  These
databases will compact and repair OK using A2007.

These same databases don't give any problems if I'm running Access
2003 under XP.  The problem is only occurring when using A2003 under
Vista and only with specific databases.  I've tried reinstalling A2003
but there is no change.

I realise that the reason is probably fairly obscure, but can anyone
have a stab at what might be going on here.  I can't put my finger on
anything that is common to the databases that are giving the problem
compared to the databases that aren't.
