Zeldor,
everytime Microsoft release a SP, MANY people claim to not install it because they promess you a lot of problems !!!
Without having testing it or even having a MS OS !!!
Just because "M$" is "Bad & EVIL" ...
It is just a tradition.
Believe me, I'm working in a company which is a specialist in systems of information (system, network, programs & developpement) and I know what I'm saying.
Ours Engineers install SPs, and yes, after checking.
But I highly doubt that Microsoft release a patch which ruins 70-90% of the games !!!
First: never see that kind of thing (and it is since DOS 5.0 & Windows 3.11 - yes, I'm OLD ...

and believe me, it was worst with W95 & 98 !!!)
Second: gamers & games editors are a BIG community and so a BIG source of money to MS, and MS don't want to angry them.
SP3 will have some problems, of course, results of the complexity of programmins a OS, but never that kind of.
QXel
P.S.: believe me when I say that I am NOT a pro-MS.
