This isn't technically my problem so I'm not going to waste my time googling it - but I was just wondering out of interest if any web people here had ever encountered permissions issues uploading from a mac to a windows server?
Got some 3rd-party people editing one of our sites that the client has brought in on the job, and any files they upload can't be accessed via the web - they blame it on the hosting we have the site on, and tell the client as such, rather than try to troubleshoot the problem their end.
