Use of the enter key in modal dialog boxes changes depending on the function. This should be consistent across all modal dialog boxes. For example, the Audio Gain box confirms changes when enter is pressed, just like clicking OK. The rest of these examples dismiss the dialog box without changes, same as clicking cancel or X (close window). This is counterintuitive as a pre-highlighed OK button implies that pressing enter is the same as clicking OK. None of these examples have a moving highlight like the Export pane.
