The following procedure will open the VB editor, then minimize it. There will be a very slight flicker as the window opens and minimizes itself.

Sub Open_VBE()
  With Application.VBE.MainWindow
    .Visible = True
    .WindowState = 1 ' vbext_ws_Minimize
  End With
End Sub

I know of no feasible way to color the security warning in 2007 so it is more noticeable. I wish it would always pop up a dialog, but in 2007 the dialog only appears when the VB editor is open. That’s most of the time for me, but of the 20% of the time when the VBE is closed, I miss 50% of the warnings.

The other shortcoming of the dialog warnings in 2007 is that, when you do get the dialog, clicking the red X does not cancel opening of the file as it used to do. The file still opens, but with macros disabled.

I could do it with VBA… oh wait…

Yep, missing the “Message Bar” was an easy job and happened more often than otherwise. But I actually prefer that more intrusive message box. I never missed that one. :o)

Thanks for sharing your thoughts on the new format of the Message Bar.

I haven’t explored the extent of the new warning. Every time I am tripped up by the gray hidden warning in 2007 (a couple times per session, it seems), I appreciate 2010′s red message.
