I have a several combo boxes in my app doing various things.  Over the last 
week, several behave differently.  The users are calling saying that they can 
no longer find their entry.  The ones that I have checked on have values 
being returned by either a stored proc, or the table they are bound to, but 
they don't return all of them any more.  They did last week, so I don't think 
I hit the limit.  
What have I done that altered their behavior?

Thanks,
Steve
