Hi davemacdo,
Flashman's last problem turned out to be that the initial path had managed to get a hidden carriage return in it, therefore making paths not match. He cleared the text and re-typed it to fix the problem.
I agree that there should be a separate setting for the base folder and I'll certainly get to that, but in the meantime make WebURL work as described using the Initial Path as the base folder, but to get the initially displayed folder functionality back, enable the 'Restore last visited folders' option in the Interface panel of the Preferences - when enabled, the current local and remote folder is recorded in the Bookmark when you close the FTP Browser, and when you open the Bookmark again both the local and remote sides will be restored.
