I have come across this tag. It seemed to me at the time that it was some sort of weird IDE bug, where it inserted that attribute because it lost track of something.

I'm pretty sure it has something to do with the position of the control. All my stuff is Flow layout, so I deleted the attribute and everything was peachy.

>Has anyone ever heard of an HTML attribute named 'DESIGNTIMEDRAGDROP'? I have a web from blowing up on this line of HTML code, but I'm afraid to remove this attribute. I'm not quite sure what it's purpose is. Please help!
