App stays on top after opening Outlook

Our main form which descends from TForm and contains your toolbar in a panel, opens a modal print dialog, which in turn opens a modal PDF save dialog if the user chose to print to a PDF.  Once the PDF is created, another modal dialog opens up to view or email the document.  If the user chooses to view it, it opens the associated PDF reader which is usually Acrobat Reader.  This comes forward fine.  If the user choose to email, it opens the default email client via JvMail.Send.  If it is Outlook, the main window of our app suddenly comes to the foreground (even above our PDF completed dialog and our Print Report dialog, all modal) and the Outlook composition dialog stays in the background.  This is also true for Windows Live Mail, so it is not specific to Outlook.  This occurs on Win7 and Win 8.1.  The app is compiled with Delphi 2007.  If our app is full screen, the user is screwed since they are locked out until the composition window is closed since it is opened modal.  When you close the composition window, the next modal windows then comes to the foreground... close that and the next once comes into view until we are back at the main window.
