Hmmm.... I'm not really familiar with what's involved with worrying about
that sort of thing. Since you mentioned "byte alignment", I ran a search and
it appears that Windows assumes that all data structures are multiples of 8
bytes. 696 is a multiple of 8, while 692 (which is the true size of the
struct, based on the number of vars and their sizes) is not. So, is it
correct to assume that Windows is tacking on an extra four bytes to maintain
the x8 rule?

Thanks,
