[1.1.1] macOS: App.focus: Occasionally: Where is osascript

[RaiMan]

Occasionally !!
My Log File :-
[log] App.focus: [0:TynonS2]

My Screen (Pity I cant load a screen shot)
Will have a box on the screen
headed Choose Application
sub heading Where is osascipt
and a list of all applications from my application directory

Whilst this is happening the Application TynonS2 is loaded by the App.focus command
The Script will then wait until the Cancel is clicked on the Choose Application box

As Sikuli is paused I have no way to deal with this box within the Script

Any Suggestions would be welcome

as I said - Occasionally !! - maybe once in 500 times
