Opening in design view breaks qry

[Razor]

Hi,

Sometimes when I change a field name, and open a
previously written query in design view, Access tells me
that the join cannot be represented in design view, and it
breaks the join.

However, by then it is too late as I don't know what kind
of join it was or on which fields. The query is then
saved without the join.

Is there any way to learn about the join properties after
it is broken?

Thanks!

Regards,
Razor
