System don't leave 'on idle'

Question

Hi!
I have i iMac that i would like to run as a Kiosk with Safari.
Got i all set up via parental controls but there is one thing left;
I would like to close all Safari windows and tabs and reopen the home page, after 5 min of inactivity (idle).
This is the script I'm working on:
global quit_after, check_every
set quit_after to 60
set check_every to 5
set minute to quit_after / 60
display dialog "Kontroll sker var " & check_every & " sekund. Starstidan kommer att laddas om efter " & minute & " minuter av inaktivitet."
on reopen
  display dialog "Kontroll sker var " & check_every & " sekund. Starstidan kommer att laddas om efter " & minute & " minuter av inaktivitet."
end reopen
on idle
  set idletime to do shell script "echo $((`ioreg -c IOHIDSystem | sed -e '/HIDIdleTime/ !{ d' -e 't' -e '}' -e 's/.* = //g' -e 'q'` / 1000000000))"
  if (idletime as integer) > quit_after then
  tell application "Safari"
  activate
  try
  repeat
  close tab 1 of window 1
  end repeat
  end try
  tell application "Safari"
  open location "http://www.google.se"
  end tell
  end tell
  end if
  return check_every
end idle
The problem is that after google.se is opened again it still think the computer is in idle, and it closes and reopens the google.se every 5 seconds (every check_every) and it goes on like that.
How do i make the system think it's not idle any more? When i move the mouse it stops...
Have placed any of the code wrong? Thanks!

Answer 1

I solved this by a not so fancy method (underlined):
tell application "Safari"
  activate
  try
  tell application "System Events" to keystroke "f" using {command down, control down}
  repeat
and when Safari is reopened with the home page:
tell application "Safari"
  open location "https://www.nordicchoicehotels.se/clarion/clarion-hotel-post/"
delay 2
  tell application "System Events" to keystroke "f" using {command down, control down}
  end tell
  close tab 1 of window 1
