Unable to advance

[Animalwildcard]

Hey there, I'm having an issue and can't seem to find a solution or anyone else that is having this problem!

I've gotten to the Treehouse, and I have hit a point that I am unable to advance. I am unable to click on the stack of papers to get the card piece task. I have tried this multiple times and each time I am still unable to click the papers in order to advance.

I've solved every other puzzle that I am able to, I just can't advance because I can't get the code for the dial machine. And it's a shame, because I do enjoy this game.

Is there a way to fix this? Is anyone else having this problem? Any help would be really appreciated!
