Hi Liuqing, This is probably a problem with the graphics driver on your computer. Updating the graphics driver may be the only way to fix it. If you resize the window does it display correctly? If you can pull down the menus, find the Help menu and try to use menu entry Help / Report a Bug.... Maybe the bug report window will be blank too, but if it shows correctly and you submit a bug report we will be able to see what graphics driver you are using. Tom
