Browser Considerations For Authors/Admins:

  • A high-speed internet connection will ensure the best user experience especially if you are working with online courseware, video streaming or large files.
  • Browser cookies and scripting must be enabled.
  • Pop-up blockers should be deactivated.

  • Claro is designed to function with an SVGA monitor display settings at a minimum of 1024 × 768 pixels. We recommend at least 1280 × 1024 pixels as the display setting. If you have the minimum settings we recommend you put your browser in full screen mode. For more information, see Browser Full Screen Mode.
  • Firewall, caching, and proxy servers and programs may need to be temporarily disabled or bypassed if authors experience issues with the system.
  • Make sure your browser is not set to use proxy settings (see Proxy Settings and Local Area Network (LAN) Settings)

  • Third-party toolbars may need to be temporarily disabled if authors experience issues authoring courses. In many cases toolbars and other add-ons to browsers can use up necessary screen space limiting the available authoring area.
  • To help with the overall performance of Claro, your Claro URL should be added as a trusted site for your browser. This URL should also be set to bypass your firewall, caching and proxy server rules.

  • Browsers will perform best if the zoom level is set to 100%.  If your browser is not set to 100% then some elements of the interface will appear out of place. For more information, see Zoom Settings on a Browser
  • Access to microphone and web camera should be enabled. If access to the microphone and web camera is not allowed then the audio and video capture features are not available. These features are used to record narration and allow live instructor video presentations.
  • Due to the heavy use of client side JavaScript in Claro using the product with Script Debuggers (firebug, safari developer tools, chrome developer tools) or traffic analyzer tools (firebug net panel, fiddler tool etc) is not recommended or supported. Having these tools enabled will significantly impact the speed, performance and possibly the output of the product.
