After 6 months of searching, I've finally obtained a copy of the Island of Dr. Brain. When I ran the executable file, it started up just fine... except the mouse isn't registering. I get the curser, just can't move it anywhere. Keyboard still works fine. So I downloaded the newest version of DosBox, started up the game (an interesting thing to note... this completely changed the sound of the music during the intro). Still no mouse. Any suggestions on how to fix this?
