Thanks Iurius for the kind words.
I was able to reproduce the bug. It happens when unlocking the door and clicking the handle while unlocking is still in process. This will get fixed in the next version.
Nice!
By the way, I have made the news of the game on our Russian site: http://questzone.ru/news/EyuuZFpyApweABPVOh
And one my friend there is asking you if you are interested in having a Russian translation of the game made :) He has translated all Carol Reed games into Russian.
