From my personal experience: SP4 solved many problems I had before with SP3. It also solved many problems I had after installing different MS or 3rd party software. I cannot say that I had a single problem because of SP4.

I installed SP5 only yesterday, so, I can't tell much about it.

>Thnx for the suggestion Paul. I had been thinking of doing that but had heard that SP4 had some problems so I have avoided it but maybe SP5 resolves all those issues?
>Have you any experience with either SP4 or SP5?
