Hello again and thank you for the info!
For the resolution, it always tries to launch in full screen at the beginning but it is not doing it in your screenshot, right? (also the black windows happens for a second when applying the resolution change, but it should not freeze there).
I have been testing different things during this time and I found the bug that made the screen to not get covered completely but I can't find any of the other... it could be a consequence of the low fps ( it probably is updating less than the 60 times per second it requires too and that may be the reason for the fast keys in the minigame, not being able to get your input correctly, etc).
Could you please try the 32 bit version? It's just to check if the JRE in the 64 bits is malfunctioning for some reason, because I don't have any other idea of what could be happening :(.
