When you start NJStar Communicator, it will normaly start the Chinese/Japanese/Korean (CJK) input bar which you used last time. But if you closed the CJK input bar before closing the Viewer control bar, the CJK input bar will not start next time. In this case, you'd have to start the input bar in either of the following two ways:

• Right-mouse-click the red NJStar icon in your windows system-try (located down the bottom right corner of your screen), then choose your input method;
• Click on the "Keyboard" icon from the VIEWER control bar (usually located on the top-right corner of your screen), then select the Chinese/Japanese/Korean input method.
