Look carefully at the Form_Load event of the form frmStart. It includes these 3 lines
Code:
SetWindowLong Me.hWnd, GWL_EXSTYLE, GetWindowLong(Me.hWnd, GWL_EXSTYLE) Or WS_EX_APPWINDOW
ShowWindow Application.hWndAccessApp, SW_HIDE
ShowWindow Me.hWnd, SW_SHOW
Why have you minimised your form? If you want to restore it use DoCmd.Restore or DoCmd.Maximize as appropriate
I only use SetAccessWindow SHOW_MINIMIZED in very limited circumstances though you can find examples of its use elsewhere in the form code
Whether you need it will depend on what you did to your form before clicking on the taskbar icon.
I realise that doesn't answer your question, but unless I know more about your setup I can't give a definitive answer.
Suggest you look at each part of the code in my app.
