Hi Rob, Thanks for the reply.
Any word on this? I did try Wix 3.5 but ran into (different) pyro problems due, I think, to it trying to create cabinets in parallel that required the same resources. If you think it might be better to persevere with v3.5 given the age of v3.0, I can give it another go. Steve On 07/01/2011 17:11, Rob Mensching wrote: > Delta patching has all sorts of issues.
