Vaadin 7.1 Drag and Drop Delay in IE10

Hi,

i have noticed that since updating to 7.1 IE10 has a delay when accepting the “drag” over a component, this can also be viewed in the vaadin sampler:

http://demo.vaadin.com/sampler/#ui/drag-drop/drag-components

One has to hold the mouse button down for ~500ms until one can drag a component.

This completely breaks an application i am working on.

Ideas?

Greetings
