Couple of things.
W2k is listed as a valid operating system for chrome, at least that is what it says on the tin !!
The reason for shifting from IE6 is that some utilities are flashing up the message that they will soon stop supporting it, whatever that means.
Although I use several machines for my work, I never delve too deeply. In other words if a programme works, I use it.
Regarding Firefox, am I right to assume that it is simply a browser similar to IE6 and can be used alongside if necessary ?
