File Delete ALWAYS asks for confirmation

A trivial problem which is driving me nuts.

I'm just doing plain old FTP uploads/downloads to a website.

I don't want to have to confirm when I replace existing files. I've gone to Settings / Transfers / Files, and set my "On File Delete" options to "Delete and Overwrite". I've also tried plain Delete. Either way, I ALWAYS get asked to confirm when I overwrite an exisiting file.

Seems like it should be a staightforward thing, but I must be missing something... can anyone help me out? Is there a way to overwrite existing files without having to deal with a dialog box every time?

Thanks,
Dave.
