>How can I issue an ALT-F4 command after the GETFILE() dialog is on top? I have tried placing the command in a Timer event but is not working. Any suggestions?

Try launching a script to do it before launching the GETFILE() to create an external timeout, something like the following; please excuse any typos, since I'm working in two of the languages I've used least recently, VBScript and VFP:

cScript = [Set WshShell = Wscript.CreateObject("WScript.Shell") + CHR(13) + CHR(10) + ;
Wscript.Sleep 20000  + CHR(13) + CHR(10) + ;
Set FSO = Wscript.CreateObject("Scripting.FileSystemObject") + CHR(13) + CHR(10) + ;
If Not FSO.IsFile("C:\GotAFile") THEN + CHR(13) + CHR(10) + ;
WshShell.AppActivate "Open" + CHR(13) + CHR(10) + ;
WshShell.SendKeys "%{F4}"  + CHR(13) + CHR(10) + ;
End If  + CHR(13) + CHR(10) + ;
WshShell = Nothing  + CHR(13) + CHR(10) + ;
FSO = Nothing]
IF FILE('C:\GotAFile')
   ERASE C:\GotAFile
ENDIF
=StrToFile(cScript,'MYVBSCRIPT.VBS')
! /N7 CSCRIPT.EXE MYVBSCRIPT.VBS
ax=getf()
IF ! ISEMPTY(ax)
   =strtofile('','c:\gotafile')
ENDIF
