I'm guessing that the LOAD_WITH_ALTERED_SEARCH_PATH means that a DLL loaded via:
hDLL = LoadLibraryEx(pathname, NULL, LOAD_WITH_ALTERED_SEARCH_PATH);
will in turn (by default) search for its dependent DLLs in their own
directory. Or maybe in the directory of the first DLL to be loaded
with LOAD_WITH_ALTERED_SEARCH_PATH, damned if I can follow the
documentation. Looking forward to doing my tax return after this.
But - anyway - that means that any extensions in the DLLs directory
will get their dependencies from the DLLs directory, but that is only
true for extensions in that directory.
