The Calendar seems to open after a very very long time, but the browser either chokes on JS execution or even memory. I will do my best to provision a machine with Windows 7 with IE9 to give more info.\r\n\r\nAny more information on this?\r\n\r\nI'm using the latest Mobiscroll Range component with jQuery."},"comment":{"url":"https://api.github.com/repos/acidb/mobiscroll/issues/comments/142219726","html_url":"https://github.com/acidb/mobiscroll/issues/353#issuecomment-142219726","issue_url":"https://api.github.com/repos/acidb/mobiscroll/issues/353","id":142219726,"user":{"login":"dioslaska","id":324318,"avatar_url":"https://avatars.githubusercontent.com/u/324318?v=3","gravatar_id":"","url":"https://api.github.com/users/dioslaska","html_url":"https://github.com/dioslaska","followers_url":"https://api.github.com/users/dioslaska/followers","following_url":"https://api.github.com/users/dioslaska/following{/other_user}","gists_url":"https://api.github.com/users/dioslaska/gists{/gist_id}","starred_url":"https://api.github.com/users/dioslaska/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dioslaska/subscriptions","organizations_url":"https://api.github.com/users/dioslaska/orgs","repos_url":"https://api.github.com/users/dioslaska/repos","events_url":"https://api.github.com/users/dioslaska/events{/privacy}","received_events_url":"https://api.github.com/users/dioslaska/received_events","type":"User","site_admin":false},"created_at":"2015-09-22T09:04:57Z","updated_at":"2015-09-22T09:04:57Z","body":"I'm testing this currently on IE9 / Win7 / VirtualBox, using multiple months and bubble display.\r\nI see no time difference if I apply the transform styling, in my test site it always appeared within 1 second. The `scrollTo` call you mentioned runs in 40ms. My guess is that it depends on page content also which is scrolled.\r\n\r\nAnother note: using `transform: translate(0,0);` is not recognized in IE9, as it is using the prefixed version of css transform, so it should be `-ms-transform: translate(0,0);` Were you testing somehow in IE10 with IE9 mode?\r\n\r\nAs a conclusion, I will include this if it helps, as `translate3d` is needed anyway for webkit browsers."}}
