Cannot seem for the life of me figure out why I keep getting this error with QPlus' plugin.

Here is the plugin:

Here is the error:

It seems to happen completely randomly. I havent figured out if its timer based or what.

TypeError: windows.isOpen is not a function
at Scene_Map.updateMouseInsideWindow (QPlus.js:892)
at Scene_Map.update (QPlus.js:884)
at Function.SceneManager.updateScene (rpg_managers.js:2024)
at Function.SceneManager.updateMain (rpg_managers.js:1983)
at Function.SceneManager.update (rpg_managers.js:1907)

QPlus script:

//-----------------------------------------------------------------------------
// Scene_Map

var Alias_Scene_Map_update = Scene_Map.prototype.update;
Scene_Map.prototype.update = function() {
if (TouchInput.isMoved()) this.updateMouseInsideWindow();
Alias_Scene_Map_update.call(this);
};

Scene_Map.prototype.updateMouseInsideWindow = function() {
var inside = false;
var windows = this._windowLayer.children;
for (var i = 0; i < windows.length; i++) {
if (windows.visible && windows.isOpen() && windows.isMouseInside()) {
inside = true;
break;
}
}
TouchInput.insideWindow = inside;
};

Tried doing a search and only found the same issue related to RMMZ. Tried that fix and same error.

EDIT: So it seems to happen once I move the mouse. Still not sure WHY.
