Visual Basic calling DLL events

When I show a non-modal dialog events are being returned to the calling application from the activeX so everything seems to be working fine.

However when I show a modal dialog events are getting blocked and are not seen by the calling application.

Attached is an example of the problem. One is a sample ActiveX dll and the other is a demo app which is using that dll.

Problems:

In dubug mode (IDE) of ActiveX dll, the demo app is seeing the Clicked event, however the event does not get fired in complied version of Dll.

Clicked Event is fired on Clicking [OK] button of ActiveX dll dialog

Need to Solve:

Demo app must get the event when clicking on the ActiveX dll dialog [Ok] button in the compiled exe.

In DLL Project
Add a form (Dialog) containing two buttons

Option Explicit
Public Event Clicked()

Private Sub CancelButton_Click()
    Hide
End Sub

Private Sub OKButton_Click()
        RaiseEvent Clicked
End Sub

Add a Class (clsTest)

Dim WithEvents mDialog As Dialog
Public Event Clicked()
Public Sub Load()
    Set mDialog = New Dialog
    mDialog.Show vbModal
    Unload mDialog
    Set mDialog = Nothing
End Sub
Private Sub mDialog_Clicked()
    MsgBox "Anu Jain"
    RaiseEvent Clicked
    MsgBox "Anu Jain111"
End Sub

Compile and register the DLL.

Create VBProject

Add form containing on Button, include reference of registered DLL.

Dim WithEvents mDialog As ModalDialogTest.clsTest
Private Sub Command1_Click()
    Set mDialog = New ModalDialogTest.clsTest
    mDialog.Load
   
End Sub
Private Sub mDialog_Clicked()
    MsgBox ""
End Sub
