When trying to insert a new record in a subform in datasheet view in 2010, it will only allow you to insert a new record in the subform if you are on the last record in the main form. In 2007, I can insert the record in the subform on any record in the main form (this is the expected behavior and it has been working for several years). The same behavior occurs regardless of database format ( .mdb or .accdb). I have checked all of the properties and they are correct. I haven't worked much with Access for about 5 years so I'm not sure if this is a common problem or something quirky with my application.
Any ideas are greatly appreciated.
