The warp of the cursor has been disabled in nxagent-3.5.0-3.
Warping the cursor on client side causes some annoying behavior. It can generate vicious loops of 'mouse move' events between the remote and local cursor with visible effects.
It can happen, for example, when trying to resize the NX window. Sometimes the resize doesn't properly follow user action when dragging the window border. In particular the window can continue to resize by itself for a while even if the user has already stopped his action.
