appskey script randomly stopped working

[becritical]

This script
AppsKey::
Send {lalt down}{tab}
sleep 100
Send {lalt up}
return

has randomly stopped working. Appskey works fine if I reassign to another key but doesn't work with this script that switches between the last two used windows in windows 8.1. I tried to upload to the latest version of ahk but nothing changes.

[becritical]

if I open ahk I can tell it performs the keystrokes
035: Send,{lalt down}{tab} (0.11)
036: Sleep,200 (0.20)
037: Send,{lalt up} (0.02)
038: Sleep,100 (0.11)
039: Return (0.83)
