Hello,

The company I work for is preparing for application testing in IE8. Previously we have been using IE6. Many of our web applications are written in .NET 1.0 and 1.1 with more recent apps written in 2.x and 3.x. I know IE8 has an IE7 compatibility mode and it says it has a quirks mode, but most of our apps were written for 6, which is not specifically mentioned. Compatibility is for 7, which had a compatibility for 6. I do not know if that is necessarily carried over to 8. In 6 quirks mode was to run 5.5 sites without a problem. With no deeper explanation on any of Microsoft's release notes does it mention quirks mode as 6 compliant or even 5.5, just a basis of what it is (specific DOCTYPEs or no DOCTYPEs).

If anyone could shed some light on how sites and apps designed for IE6 should run in IE8 would be greatly appreciated. If anyone else has made a similar move how smooth was the transition?

Thanks.

JQuery UI sortable is slow in IE8, but works good in IE7 and IE8 compatible mode

JQuery UI sortable (including demos) are slow in all IE8 I can test, but runs smoothly in IE7 and IE8 compatible mode. The more complex is a markup on the page, the more IE8 is slowing down (that's I can understand, the DOM tree became more complex). I'm using JQuery 1.3.2 and JQuery UI 1.7.2 (tested… >>> More
