Why do I see memory usage increase when using Internet Explorer 7 to view PowerChute Business Edition v9.1.x Agent?

Issue:
Internet Explorer 7 memory leaks / memory usage increases when using the PowerChute Business Edition v9.1 and above Agent.

Product Line:

Environment:
Microsoft Windows OS with Internet Explorer version 7 (IE7)

Cause:
JavaScript memory leak.

Web pages to articles that list the types of memory leaks that can occur in JavaScript:

Solution:
  IE7 is not a supported web browser with PowerChute 9.1.x You can resolve the issue by upgrading to the latest version of Internet Explorer.
NOTE: Neither closing the IE tab with the Agent interface or logging out of the Agent solves this problem.
