I play Age of Empires II (no expansions installed on this machine), and something weird happens very often on my old Windows 7 PC.
After a few minutes of gameplay, AOE II auto reverts to the desktop without any user input. First, the screen turns black for around a second, then it shows my desktop. In an hour's time, this happens around 20-something times, and can get annoying. The game continues to play in the background. Then to go back you have to click on the icon.
Please help. I have dealt with this bug (?) for about 4 years.
