If you are using Internet Explorer 8 to connect to an S2 access control system integrated with exacqVision, a “Stack overflow error 0” message might appear repeatedly. This issue occurs more often if the S2 and exacqVision systems are connected on the same LAN, and it is caused by the way Internet Explorer 8 handles exacqVision JavaScript.
To avoid the error message, upgrade to S2 Release 4.1, Build 453 firmware, which is available from S2. Alternatively, you could connect to S2 using the Mozilla Firefox browser.
