Whenever clicking a URL linking to another Access database in a URL field, Access will create another instance of itself.
Say, a database named ABC.accdb contains a field named URL.
The value of a record's URL is DEF.accdb. If that field is clicked, Access will create two windows: DEF.accdb and ABCD.accdb. Now we have two instances of ABC.accdb.
The value of another record URL in ABC.accdb is XYZ.accdb. It that field is clicked, Access will create two windows: XYZ.accdb and ABCD.accdb. Now we have three instances of ABC.accdb.
Why does Access create any addition instance of itself whenever a URL linking to another Access database is clicked?
