[ntp:questions] still not able to get NTP to sync on windows 7 even w/ more updated binaries

Here are some updates based on overnight running of "ntpq -p" every 10
seconds.
win7 is running w/ minpoll=maxpoll=32, Linux is running as just
standard NTP install (fedora 12).

win7 NTP is version 4.2.7p98 overlayed on top of Meinberg install.
Linux NTP is version 4.2.4

Offset, delay and jitter values from ntpq -p are plotted below.

What is seen is that after flaying around wildly for some time win7
starts to settle down, though zooming in shows that it is still
swinging around quite a bit though in smaller steps.
