user32.dll should already be loaded and the msdn documentation doesn't actually specify what happens if you call LoadLibrary on a dll which is already loaded, though I see no reason why it would not work ok. Did you ever try using GetLastError ?

You can always try using GetModuleHandle to get the handle to the already loaded dll if you really do want to use GetProcAddress. (though I do agree with squidge that this really isn't necessary).
