Modeless dialogs stay around a lot longer than during one function
call. Except yours, which is destroyed almost immediately because
aboutDlg goes out of scope when the function returns. Use a member
variable instead:
m_pAboutDlg = new CAboutDlg;
Then you'll need code somewhere else to ->DestroyWindow and delete
m_pAboutDlg.
