Thanks to all. I will look into Transmit. I'd tried Fetch, and that same day I experienced the most serious Apple crash I'd ever had. I know Fetch is well regarded, so it may have been pure coincidence. I did upload successfully using Fetch.
Via OSX I have used the syntax christian described, and I can download from FTP. But when I try to upload, I get that "[file] could not be moved because [target FTP folder] cannot be modified." I assume I'm logged in to the FTP site because I'm accessing a password-protected folder. I log in on XP the same way and upload freely.
On OSX I tried alternating the passive FTP setting in Network preferences to no avail. I don't know how to disable a proxy. I think "Transmit" will be my next step.
