Open from Creative cloud?

Despite how prefs are set, one can use a script to force a local open window (which does not offer all of the standard features of the default open window). A custom keyboard shortcut can then be applied to an installed script.

try {
    selectFile = File.openDialog("Please select the file or files:", Multiselect = true);
    for (var i = 0; i < selectFile.length; i++) {
        var openFiles = app.open(File(selectFile[i]));
    }
} catch (error) {}

As preferences can become corrupt and or regularly reset to defaults for support/troubleshooting, I have created an action to reset preferences and other common settings. Before recording you need to set the control to be opposite of the intended result, then when you record the action it will correctly record the change to the required setting.
