Tabbed Panel Issues with CS5,CC2014,CC2015?

I have created a script with TabbedPanel in ESTK CC,works fine in afx CC 2014, but it seems like there are some issues with other versions(CS5 and CC2015).

Can someone help how to universalize the tabs and bounds???

Below is my Code briefly for tabs.

//

//

//

function buildUI(thisObj) {

var myPanel = (thisObj instanceof Panel) ? thisObj:new Window('palette', 'Stress Reducers',undefined, {resizable: true});

myPanel.timeSavers= myPanel.add("tabbedpanel", [0,0,400,300], 'Stress Reducers V1');

myPanel.timeSavers.cProject_tab= myPanel.timeSavers.add("tab", undefined, "Project");

myPanel.timeSavers.MyTools_tab= myPanel.timeSavers.add("tab", undefined, "MyTools");

myPanel.timeSavers.Explorer= myPanel.timeSavers.add("tab", undefined, "Explorer");

myPanel.timeSavers.Others_tab= myPanel.timeSavers.add("tab", undefined, "Install");

return myPanel;

}

var myToolsPanel = buildUI(this);
