I have doubts if I should post this here or in the "help" discussions, so, sorry if I got it wrong.
As the thread title says, I have been encountering a weird technical problem with Puzzle Agent.
Everything worked fine until the very end, besides the fact that, when quitting the game, the "yes" and "no" squares were without text and you could only see their colour and the bug that several people reported about the sleigh disappearing if you returned to the factory after a certain event almost at the end.
But, when I get to the actual ending, at a certain point after you are back in your office and Tether's boss tells him he should not worry about Isaac's disappearance, since the local police will take care of it and his mission to reopen the factory was accomplished. Then Tethers looks dubious and the scene fades to black.
Then credits should probably be rolling but the screen goes black, while the computer seems to be loading, but nothing happens and the only button which works is the space (in fact the word "paused" comes up on the black screen and goes away if you press space again). I've tried waiting but it was pointless and in the end I had to use ctrl alt del to get out of the game. I tried loading it again and I was just before the last puzzle, I solved it again and the same thing happened. I know it is not a major problem, but I may be missing a part of the ending, plus I wanted to signal this for future reference.
