NIS new version check

running NIS 21.7.0.11  -  win 7 64 bit

with all the issues users are reporting with forced update to NIS ver 22.x, my issue seems to be unique, hopefully not !

i just ran a 'check for new version'  -  results page state that i have the latest version.

as we all know, NIS ver 22.x is the latest. (maybe not ??)

in fact, NIS 22.x was pushed to my win XP system when i turned it on, a day or two ago.  SURPRISE, SURPRISE !!!

i quickly turned off the auto update setting on my other systems.  i didn't want to auto update to a new version by surprise.

have i uncovered a 'BUG' in the NIS ver 21.x new version checker ??  

has Norton backed off on NIS ver 22.x as a 'new version' or a forced update (auto update turned on) ??

will i need to MANUALLY download NIS ver 22.x ??

any advise would be appreciated
