So I must have
I had the same problem. Here is what I did to fix the problem. Outside of the game, in regular windows, I had changed some of my mouse settings such as
displaying pointer trails. After returning all of my mouse properties back to default in windows, I returned Baldur's Gate and voila!, my mouse pointer had finally arrived! I hope this helps anyone with this problem as well. Good luck.
So I must have done something wrong the first time I troubleshooter the issue. Cus I swear I checked all that.
Anyways so I downloaded Baulders gate 1 and my mouse ALSO disappeared. SO I went back and checked all the things I thought I did the first time and the 'display mouse trails' was checked, even though I swear I un checked it. SO I unchecked it and all is fine now.
