the 2nd line needs to direct towards your SC Directory (so C\"Games\Starcraft"\"StarCraft.exe" for a lot of you)
When you save the file, save it as a .bat file and use that to launch Starcraft. It will terminate explorer while SC is running, and when you close SC explorer automatically restarts. This is the only fix i have found that works for my setup; Windows 7, Build 7100 w/ Nvidia 7950 GT.
Hope this works for you!
Thank you VERY much for this fix. It works perfectly.
Note to everyone that uses this. Because it closes explorer, you wont have access to your start menu or other programs while playing SC. If you have a program (e.g. Firefox) already open, though, you can Alt+Tab to FF and use it just fine.
