Hi Paul, I can't think of any changes that would have caused the slowdown you're seeing. (I tried to reproduce the problem, but can't.) Could you please answer a few questions to help me try to narrow it down:
- Are you building applications for the web, or for AIR? - Are you on Windows or Mac? - If you run a CPU monitor (such as Task Manager on Windows, or Activity Monitor on Mac), do you see a lot of CPU being used up? - Does this reproduce even with small examples? Can you post an example that reproduces the problem? Here is a small sample app that I tried: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:DataGrid dataProvider="{data}" toolTip="blah blah"/> <mx:XMLList id="data" xmlns=""> <item name="First item"/> <item name="Second item"/> <item name="Third item"/> <item name="Fourth item"/> </mx:XMLList> </mx:Application> I ran that with F11 (debug), and then hovered over the datagrid; the tips came up quickly.
