Ensure window focus at launch

I’ve been struggling to get an enhanced window to be focused after launching the script from Alfred or Keyboard Maestro. I tried executing it from Alfred’s main thread as a NSAppleScript and through the command line as /usr/bin/osascript var_viewer.scptd but regardless, when the window launches it is not focused. Below is a example (note how i have to click the window for it to become active):

DTPwindow-focus

This issue does not happen when executed in Script Debugger, so I assume the issue is related to how the current application is osascript (not being an application which can be frontmost) when executed from the command line, Alfred, or Keyboard Maestro. The whole script is below, any input would be great, thanks!

Maybe you can add a activate me statement after the dialog display?

I used ( some assembly required ):

activate application runningApp
tell application “System Events” to set frontmost of process runningApp to true
display dialog "Sent " & countPics & " screen pictures to " & recipientAddress giving up after 4
