I discovered that, when I start the game, the screen is black or dark blue instead of showing the original title screen, even though the music still plays and I can still press "enter" to start the game. I found further that the usual text that shows up at the beginning telling the player about the controls was also absent, along with the "Pause" and "Game Over" text for those screens. However, I also discovered that when I activated the task manager, the text came back.
This may be due to the fact that I am using a new computer and there may be some bugs related to the interaction of this particular computer and the game program. However I thought it was something you would want to know about
