Replying to [ticket:5741 EddieMachete]:
Auto-complete fires requests indefinitely when running on a browser on Windows 7. The issue happens when requesting data from either local or remote data sources. When attempting to request data through ajax the system just chokes under the vast amount of requests being fired. Firebug shows requests being fired every half a second on the Jquery demo page and in our application. We haven't noticed the same behavior on Windows XP boxes. We tried Firefox 3.5.4, Internet Explorer 8.0.7600, Chrome 5.0.375.7 Beta
We have to apologize for issuing this defect. We have been experiencing this problem for 3 weeks but it seems to be a Windows 7 issue and not a browser or jQuery problem. At our work environment our Windows 7 machines seem to be firing certain system events intermittently. We have noticed that the task bar seems to be refreshing too many times when rolling over its items. Some system ui components used by the web browsers seem to suffer from this problem too (like text fields and select boxes). After re-starting the machines the problem disappears but it comes back after having the system running for a few minutes.
In conclusion this seems to be a Windows 7 issue, not jQuery or any browser.
