There are 3 ways to do this, screen resolution window, run in Compatibility Mode, and a .bat file.
Step 1: Screen Resolution Window
Now just run starcraft and it might work. If it doesn't try the next solution.
Step 2: Compatibility Mode Part 1
Now click on the Compatibility tab.
Step 3: Compatibility Mode Part 2
If this doesn't work you might want to uncheck the first box. You might want to try many different combinations.
If this doesn't work, try the last solution.
Step 4: .BAT Solution
First, open notepad from your accesories.
Now copy this code into it:
taskkill /f /IM explorer.exe
And save it as Starcraft.bat (all four lines). Make sure not to put starcraft.bat.txt. Now double click on the .bat file.
