Have now been playing with Softgrid for a bit and remain gob-smacked. However, I can't seem to find much detail on inter-application stuff. I can't quite get my head round whether an app that connects to Office, for example, will put it's hooks into 'real' office on the TS or must have Office sequenced with it. If the latter, does that mean you have to sequence Office with every application that references it, or just once? If you have to do it every time, then how do you handle eg File Extensions? If there is only one virtual copy of Office on the Q: drive, and half-a-dozen apps accessing it in their various ways, are you not back to one of the original problems - that their various ways of interrelating with Office may interfere with each other? I understand that 4.5 will help with all this, but presumably people are doing something now? On a more general note, can anyone point me at 'non-official' documentation similar to "The art of sequencing" by Sean Donahue etal? Nick
