Appendix 1.6. Buttons Display in White

The Windows CE 3.0 operating system does not automatically adjust daylight savings time correctly; therefore ‘Daylight Savings Time’ should be disabled on Windows CE computers. Failure to do this could result in cookie expiry when a transition occurs. This will result in the screens indicating that the display objects are offline (white).

White buttons indicate (amongst other things) expired cookies.

Ensure Daylight Savings Time is disabled. Set the time and date correctly. Now refresh the page and wait a few seconds. If the buttons remain white then repeat this refresh a few times.

Appendix 1.7. Cookie Length

The following statements are true irrespective of the operating system of the browsing computer.

For many of the Sentry Controls, the HTML screens get data from the LANServer in the form of cookies. The maximum cookie length is 3500 bytes. If the cookie length exceeds this limit then the screens will not update correctly.

The driver prints a message in the error log if the cookie length nears this limit.

WEB: #60 Err. Web Pages won't update properly. Cookie Length Max/Rqd=%d/%d
