Thanks for the info. It got me on the right track. It seems to depend on which method is used to simulate mouse or keyboard. Here is what I found out: Moving the mouse with SetCursorPos(x,y); does not wake up the display Moving the mouse with Mouse_Event(MouseEventF_Move,100,100,0,0); does wake up the display Simulating the Keyboard with PostMessage(progname, WM_KEYDOWN, VK_F5, 0); does not wake the display Simulating the Keyboard with Keybd_Event(VK_Shift,1,0,0); does wake up the display James _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
