Frequently Asked Questions:

• Java applet is not loaded. The applet area is a gray box with a red 'X' (or just a gray box):
       The watershed delineation Web-GIS based applications use Java applet as map display, which requires user to have up-to-date Java Runtime Environment. It is a free download from Java Software. Simply click on the 'Download' button to install the latest Java Runtime Environment on your computer. Installing the latest J2SE can solve the 'java applet loading failed' problem in most cases. After installation, close down your web browser and relaunch the site.
        Sometimes, when java applet encounters a problem, user should clear his Web browser's cache, then reload the page to start a new session. Simply reloading the current page without clearing the cache would only reload the problematic java applet settings again, hence problem continues.
• Double click in Internet Explorer? NOT!
       Recent versions of the Microsoft Internet Explorer (IE) disabled the automatic recognition of Java Applet, along with other Active X components. Hence, in IE browser, user should first do a single left-click anywhere within the Applet area to gain focus, then subsequent clicks will be applied to the Applet itself. Users are recommended to use the Firefox browser, which does NOT require the initial click to gain focus.      Please note that throughout this entire site, all operations are done with single left click, except for the user digitizing page, where user should use a single right click to initiate landuse/BMP assignment process. NO DOUBLE CLICK is needed throughout this entire site.
