ginsonic's code doesn't free the pidl -> memory leak!

Tasomia's code does free the pidl, but too early, you're freeing it before it is actually used.

This one works fine on my XP, didn't test it under other OSs, though:

  WinExec('explorer.exe ::{20D04FE0-3AEA-1069-A2D8-08002B30309D}', SW_SHOWNORMAL);

Regards, Madshi.
