Phrog30:
I forgot about disposing of the forms that I add to the panel.  I thought this would be easy but it takes several seconds to dispose of one form.  Here's what I'm using now:

--- Code: ---       
                Dim x As Form
                x = CallForm.GetFormByName(m_FormToOpen.Name)
                If x IsNot Nothing Then
                    _0000_Main_Parent.lbl_Display_Name.Text = x.Text
                    x.TopLevel = False
                    _0000_Main_Parent.pnlParent.Controls.Add(x)
                    x.Show()
                    x.BringToFront()
                    x.Focus()
                    'Remove all but this control (form), do last to prevent blinking
                    For i = 0 To _0000_Main_Parent.pnlParent.Controls.Count - 1
                        If i > 0 Then
                            Dim ctrlName = _0000_Main_Parent.pnlParent.Controls.Item(i).Name
                            _0000_Main_Parent.pnlParent.Controls.Item(ctrlName).Dispose()
                        End If
                    Next
                End If

--- End code ---

If I comment out the dispose, it's quick as quick could be, but once I let it dispose, it takes seconds to complete.  Any ideas and what is wrong and/or how I could do it different?

I think I'm getting there, one thing I can't seem to get is form.owner.  I have reusable popups that when I display I set the owner.  I like the way this works.  But, on a dual monitor system if I want to open this popup from another display I want to display on the parent where the call button is.  I would have though simply changing the owner would work, but doesn't.  Is there a trick to changing the form owner?  Note, I don't close these popups, but hide them so they open faster next time, plus they open in the same spot they were closed.  Any tips on this is much appreciated.

I am not sure if this is any related to what you are doing or asking about but check the idea Archie is using here:

Thanks, but that's not what I was looking for. I have since gotten things figured out to a point. I may post what I have when I get further along.

Phrog30:
Here's a link to an application that has multi-monitor support (up to 4):

The forms display automatically if you have a multiple monitor setup.  If you only have 1, then it will only display one.  I use mdiparent.  Right now I have the initial forms hard coded.
