Hiding the Navigation Pane cause a problem when exiting the database - ms-access

Question

I just found something strange with MS-Access 2016. I have a database with 2 forms: one hidden, one for a menu. The autoexec will open the hidden form and that one will open the menu form.
I unchecked some options, under Current Database e.g. [Display Navigation Pane] and [Allow Full Menus].
I have an exit button/command on the menu form. On Click, it calls DoCmd.Quit. But before exiting, I am getting an MS-Access window asking for the parameter that is normally when the form open, not when it is closing.
After doing a lot of testing and I mean a lot, I realised that the problem is related to the fact that I am disabling the [Display Navigation Pane]. If I keep the navigation pane, but instead I unchecked all Object Type, then everything works correctly.
So, my question is why disabling the navigation pane can create something like that and is there a way to fix it?
Yes, my solution works, but I don’t like it since users can open and close the navigation pane using the shutter bar; nothing shows but it is still distracting and users can call for support.
The problem is not related to the fact that the first form is hidden, but because it is open. If I add a DoCmd.Close acForm, “F_Parameter” before my DoCmd.Quit then it works.
It is easy to reproduce the problem:
Create a new database
Create two forms:
F_Parameter
F_Menu
Create a Macro named Autoexec:
OpenForm
Form Name: F_Parameter
Window Mode: Hidden
In form F_Parameter create an event On Load
Private Sub Form_Load()
DoCmd.OpenForm “F_Menu”
End Sub
In form F_Menu create a Button named Btn_Exit with an event On Click
Private Sub Btn_Exit_Click()
DoCmd.Quit
End Sub
In form F_Menu create an event On Load
Private Sub Form_Load()
MsgBox “Hello”
End Sub
go File, Options, Current Database and
uncheck Display Navigation Pane and
uncheck Allow Full Menus
Save, exit and open the database:
You will get a “Hello” because the F_Menu form open, now click on the exit and you will get another “Hello”. This second one should not be there because the form should be closing not opening.

Answer 1

I was able to reproduce the issue described. I don't think it has anything to do with the Navigation Pane.
This is happening because while the DoCmd.Quit event is occurring, the hidden F_Parameter form is becoming "unhidden" in order for Access to close it. This causes the F_Parameter Form.Load event to run, which is essentially opening F_Menu, thus causing the Form.Load event on F_Menu to run.
I was able to solve this by first explicitly closing F_Parameter, then quitting:
DoCmd.Close ObjectType:=acForm, ObjectName:="F_Parameter", Save:=acSaveNo
DoCmd.Quit
