I would develop with what you are planning on running for production. I still can't import the DCworkflow example from the CMFCollector from recent versions of all products on my win2k system. I believe it's because the custom Workflow example was exported from a linux machine. There was a problem with the dir paths \ for windows and / for linux. Another thing I seem to notice is that there is more support from the core people for linux. As evident from some past comments. So for the most part you can mix and match the two inviroments, but if you plan to do some serious work that might involve some magic coding. Good luck! hth, - James _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx
