MabiPro: The Authentic Old-School Mabinogi Experience

I just installed the game and got into the log-in window where I can't see my mouse cursor.
The game opens up in full-screen mode.

Any help would be appreciated, thanks!

Thanks Drahan, that worked and also changing compatibility mode made the cursor show up.

Enemies have been doing that in live as well from my experience. I think it has something to do with how combat works in Mabi.

How I see it, once the game sees your position is close enough to the attacking goblin and you have not prepared a skill (like Defense or Counter) to counter the goblin's attack, the game immediately moves on to the goblin's attack animation. If you were to attack it at the same time and had a faster attack speed, the goblin might stop its attack animation in favour of showing its animation when being hit.

Someone with a better understanding of the combat and coding could probably explain it better than I did or even prove me wrong. This is just my interpretation of what is happening in your video.

I suggest to brush up on monster AI so you can better predict how to counter and come out on top. I like Mabinogi's combat because it rewards you for understanding each monster's AI to the point where you could be pretty much untouchable as long as you utilize your skills and knowledge.
