Hey Noel, thanks, I was aware of that so will not be asking for support on this XP install; I'll be using X2 on a newer Win7 machine for the most part, but I still have XP on this old desktop and thought it would be interesting to see if the new beast would run. It does, but it's more 'genius' than 'seamless' so far... however, I'm probably not the only one around here with an XP machine still in service, so it might be interesting for others to get a bit of a headsup on the state of things in terms of whether X2 is usable under XP or not.
I did manage to get a mix kicked out, but there were quite a few random crashes doing things like opening the multidock... so given that no-one will be testing or working on these issues, I'll probably plan on upgrading the OS on this machine at some point if it looks like I'll be using X2 here. It's a tradeoff - the XP/X1 combination has been pretty good here, but after a few months working on X2 I expect it will be tough to go back - that's usually how these things go!
