javascript - Photoshop ScriptUI: Show a dialog window, close it, show it again gives an empty full size window -

in script photoshop cc 2015 (windows 10), written in javascript, processing layers of active document in loop , want show setup dialog in each step.

for simplification, take following working example. window defined outside loop, , among other steps stripped here, window shown once every step in loop:

#target photoshop  var w = new window('dialog', 'title'); var b = w.add('button', undefined, 'ok');  (var = 0; < 3; i++) {     // other code     w.show();     // other code } 

when execute it, small dialog window 1 "ok" button appears, expected. can close using "ok" button. but every consecutive w.show() produces blank window fills entire screen, no controls whatsoever. can closed using esc key.

i tried overriding b.onclick event , manually call close(), did not change anything.

upon inspection of w variable, obvious bounds, respectively location , size somehow got changed. tried resetting these values previous state, , window size restored. however, button still not visible.

am missing something? how can dialog window show correctly more once?

try code, works me photoshop cc + osx.

w.close() destroy dialog window, should create again.

press button named 'ok', press return key same w.close().

#target 'photoshop'    (var = 0; < 3; i++) {    var w = w();    $.writeln(w.show());  }    function w () {    var w = new window('dialog', 'title');    var b = w.add('button', undefined, 'ok', {name:'ok'});    return w  }
