I am building an app with heavy media files. I am at a crossroads. It either needs a hefty messy pre-caching system or it needs to be bundled together using an HTML to EXE app. The EXE app is preferable. However, the app has a control panel that runs in a second window. At the moment, the user opens the control panel, moves it to another display monitor, and can control the main app. The javascript uses window.opener.ParentFunction() to trigger anything it needs in the main app.
