[Plugin: CubePoints] Cubepoints crash widgets in opera

Hello, after cubepoints plugin update and activation I’m not able anymore to move my wigets that are in same row that is cubepoints widget. When I remove older wigets from sidebar when cb plugin is active it causes sidebar crash and all older widgets are being removed.

That problem is on Opera. In Fire Fox it works fine. Before cb plugin update it works without errors.

I have wpmu 3.1.2
