When running the Visual LANSA Framework on the browser you may see this window being displayed:

Example of Windows displayed

This is a Visual LANSA Framework "AutoSignoff" window which detects if a VLF browser session has been closed. If a browser session has been closed it will send the required signoff message to the web server.

For a full description of the AutoSignoff functionality, refer to What is the AutoSignoff button that appears on my task bar when executing a Web browser application? in the Frequently Asked Questions section of the Visual LANSA Framework Online Guide.

The AutoSignoff window is generally quite small and can be left opened or minimized.

However, to avoid:

  • users closing the window by accident
  • users enquiring about or being confused by its presence

it can also be hidden by using an Internet Explorer option:

It Internet Explorer, under Tools and Internet Options and Security tab folder, you can list your LANSA for the web server as a Trusted Site.

  1. Select 'Custom Level' for 'Trusted Sites' to open the 'Security Settings' window.
  2. Look for the option 'Allow script-initiated windows without size or position constraints'.
  3. Set this option 'Allow script-initiated windows without size or position constraints' to 'Enable' will hide the AutoSignoff window.

You can use this option in IE6 and IE7 to hide the AutoSignoff window.
