Alt-F6 no longer stalls the game on Windows.
Game now works correctly on versions of Mac OS X which do not support 256-color mode.

Make sure you have "Hide extensions for known types" unchecked under Explorer Folder Options.
If you own only StarCraft, copy "INSTALL.EXE" from the StarCraft CD to your StarCraft folder and rename it to "StarCraft.mpq".
If you own StarCraft: Brood War, copy "INSTALL.EXE" from the StarCraft: Brood War CD to your StarCraft folder and rename it to "BroodWar.mpq".
