            Description

            Using the application provided by the user, these are the results:
                - ICEfaces 1.6.2: After changing pages of paginator 30 times, no visible slowdowns for the menuBar
                - ICEfaces 1.7Beta: After change pages 15 times, submenus now takes about 4 seconds to appear. And in the meantime, browser uses 100% of CPU.
                                                    After changing pages 30 times, slowdown continued to increase. Now it take about 10 seconds for submenus to appear.
                                                    Note: The time it takes for the submenu of the first top-level child to appear never increases.

              Testing shows that this is limited to IE6 and doesn't appear to be related to a browser memory leak:

              Results with IE7:

              • 1.6.2: No visible slowdowns after 50 page changes
              • 1.7Beta: At start, submenu takes less than a second to appear
                After 15 changes, submenu takes about 4 seconds to appear
                After 30 changes, submenu still only takes 4 seconds to appear
                After 50 changes, submenu still only takes 4 seconds to appear

              Avoid accumulation of event listeners.
