LMS restart takes very very (very!) long on fast Win7 server

Hello fellows

When I have to restart LMS, this takes way too long. A couple of minutes. Restarting the entire computer (including LMS) is much faster!

I use:
Logitech Media Server Version: 7.8.0 - 1337855496 @ Wed Jun 6 03:15:16 PDT 2012
Windows 7 pro 64 bit (Intel i7 @3.2ghz, 8gb ram, SSD HD for program files)

I believe it is in particular shutting down the server that is so slow. Starting again is comparatively fast.

Any idea what may be wrong with my installation?

Thanks!
