Change Safari Download Folder issue

I have a routine that changes the default download location in Safari.

My issue is that the first time I try and download after running the script that changes it a window appears that asks me to “confirm your file download location” . As this is part of an automaton script I don’t want to have to confirm. In testing (when I have not reset the downloads to the default folder ) it does not ask again.

The window I referred to looks like a finder window the header caption is as I described and at the bottom I have open and cancel buttons. What I need to do is programmatically hit the open button.

The script below changes the folder

[AppleScript]
on SetDownLoadFolder()
set Thefolder to alias “Macintosh HD:Users:petermitchell:Dropbox:”
set Dfolder to quoted form of POSIX path of Thefolder
tell application “Safari” to quit – Ensure Safari quit’s using repeat loop
tell application “System Events” – One delay makes the script stable
repeat while application process “Safari” exists
delay 0.1
end repeat
end tell
do shell script ("defaults write com.apple.Safari DownloadsPath " & Dfolder) --Change Default
tell application “Safari” to activate
end SetDownLoadFolder

Sorry once again not thinking properly the window is not of course from finder but Safari. Once I figured that out easy enough to issue the correct command.

Juts in case anyone is as thick as I.

[AppleScript]
tell application “System Events”
tell process “Safari”
click button “Open” of window “Open”
end tell
end tell
