How to handle the property setting Single Form in a Sub Form

[Simon]

Dear reader,

I now confronted with the following effect.

There are three forms: Form-1 mainform, Form-2 sub and Form-3 sub in Form-2.

Form-1 Default View Single Form

Allow Form View Yes

Allow Datasheet View No

Form-2 Default View Single Form

Allow Form View Yes

Allow Datasheet View No

Form-3 Default View DataSheet

Allow Form View No

Allow Datasheet View Yes

By opening Form-1 the sub form Form-2 and Form-3 are visible as Single form
with Form-3 as DataSheet and that is correct. But if I now switch to a other
record in Form-1 by picking a record in a combobox than Form-2 change into a
DataSheet while the property Allow Datasheet View of Form-2 is set No.

Is there anyone who knows how to avoid this change in Form-2 from Single
Form to Datasheet?

Thanks for any help.

Kind regards,

Simon
