All worked fine until I put something else on the page.\r\n\r\nWhen I navigate across my site, I get nothing untoward - an initial spurt of CPU that settles quickly. However, when I click the icon button used for the the paper menu, in Chrome, the CPU immediate shoots to 70% then steadily rises to 85/95% where it stays. This occurs in Chrome  41.0.2272.118 m, and not in Firefox 37.0.1.\r\n\r\nI stripped the page back to an htm, dropping the aspx stuff, javascript and css with no success. I then copied your demo html (apart from the CSS). Again, this This works fine on its own, but as soon as I add an article (my terms and conditions), the problem reoccurs. The arcticle is pure html which has been validated - it is 4500 characters (around 600 words), which is not big in at all.\r\n\r\nI've now exhausted all my own answers - the code runs on Chrome without the additional text, it runs with the text on Firefox, but it chews the CPU everytime on Chrome after I hit the button.\r\n\r\nAny help or advice would be appreciated.\r\n\r\nI'm using Visual Studio 2010 on XP, with the dev environment running IIS Express 7.5.\r\nPolymer has been installed through nuget and seems to work ok otherwise.\r\n\r\n\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/Polymer/polymer/issues/comments/93728212","html_url":"https://github.com/Polymer/polymer/issues/1413#issuecomment-93728212","issue_url":"https://api.github.com/repos/Polymer/polymer/issues/1413","id":93728212,"user":{"login":"pflannery","id":1727302,"avatar_url":"https://avatars.githubusercontent.com/u/1727302?v=3","gravatar_id":"","url":"https://api.github.com/users/pflannery","html_url":"https://github.com/pflannery","followers_url":"https://api.github.com/users/pflannery/followers","following_url":"https://api.github.com/users/pflannery/following{/other_user}","gists_url":"https://api.github.com/users/pflannery/gists{/gist_id}","starred_url":"https://api.github.com/users/pflannery/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pflannery/subscriptions","organizations_url":"https://api.github.com/users/pflannery/orgs","repos_url":"https://api.github.com/users/pflannery/repos","events_url":"https://api.github.com/users/pflannery/events{/privacy}","received_events_url":"https://api.github.com/users/pflannery/received_events","type":"User","site_admin":false},"created_at":"2015-04-16T13:00:55Z","updated_at":"2015-04-16T13:00:55Z","body":"@johnohara have you tried in incognito mode? and have you done a CPU profile snapshot from the chrome profiler tools?"}}
