Very slow dragndrop in IE using DragDropManager

There are 2 realizations of DragDropManager in Ajax Controls:IEDragDropManager &GenericDragDropManager.

GenericDragDropManager works fine. But IEDragDropManager works slow, very slow. If I forcedly use the GenericDragDropManager for IE browser every works fast. It's clear that IEDragDropManager has some realization issues.

What's the problem and when it will be fixed?

Could be because you're running in debug mode... if so one of these:

1) Set<configuration><system.web><compilationdebug="false">in your web.config

2) Set theScriptMode="Release"property on the ScriptManager component

<asp:ScriptManagerID="ScriptManager1"runat="server"ScriptMode="Release"></asp:ScriptManager>

Either way, you should end up with the release version of the javascript coming down to you which is A LOT faster!!

Yeah, it's helped a little. But the draggins is still too slow and not acceptable for real world.

The problem isn't solved.
