Works as expected: - Start PV, click on the Decoders button, the subwindow appears. - Click the Decoders button again, the subwindow disappears. Doesn't work as expected: - Start PV, click on the Decoders button, the subwindow appears. - Create a new session window, click the Decoders button. The new session will not get a Decoders subwindow as expected, the click will appear to have no effect. When clicking the Decoders button *again*, it will appear.
