Hi.
This may be a bug related to resolution detection when having multiples monitors connected.
I'll check this, but in the meanwhile you can try to force windowed mode. Go to the folder "C:\Users\YOUR_USER\AppData\Local\PuzLogic" (replace C with your drive's letter and YOUR_USER with the user name) and in settings.ini change FULL_SCREEN="1.000000" to FULL_SCREEN="0.000000".
I hope it works and I'll let you know when I have a fix for this.
Best,
Eduardo
