Programs with an overlay can cause Blizzard games to crash if they are not fully updated, while others may cause crashes even if updated. If updating the program does not help, disable or uninstall it before playing. Some examples of these programs are:

  • Airfoil™
  • EVGA Precision™
  • Mumble™
  • Taksi™
  • Dxtory™
  • MSI Afterburner™
  • RadeonPro™
  • XFire™
