[h-e-w] problems with emacsW32

[Christian.Strobl]

hello,

i am using emacsW32 and i think i have made some mistakes with the
installation or configuration
1) every time i open a new file with "send to" a new
emacsclientw-process is starting, f.g. if i open 10 text-files, there
are 10 or 9 processes. but thats not the problem. the problem is that,
if i close emacs with c-x c-c, all emacsclientw-processes are still
there.
2) if i want to insert a date from the calendar, f.g. with i d, emacs
shows the following error message: Symbol's function definition is void:
insert-diary-entry
3) if i want to use ediff, emacs shows the following error message:
apply: Searching for program: no such file or directory, diff. but there
is program called diff.exe in the folder
C:\Programme\Emacs\EmacsW32\gnuwin32\bin

i am using the following emacsW32 version

GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600)
 of 2008-03-25 on LENNART-69DE564 (patched)

thanks and greetings from munich
