I just started to analyse this puzzle: http://de.lichess.org/training/opening/4149
and put Nxe7 on the board. But on Qxe8 the queen jumped back, so I repeated (this sometimes happens with lag), but then I got this: http://www.fotos-hochladen.net/view/puzzle4149analy8t5rkh7ly0.png
In Opera as in Firefox. Anyone else, who observes the same weird behavior?
