How did the elections office get a path to a file on your hard drive?

In a traditional URL what you have is good, which explains why it works
well in a browser.
"file://" is the service protocol specifier, and "/Users/jimhurley/..."
is the path to the file.
LiveCode's URL syntax for working with local files isn't quite the same,
though. In LC, we do need the "//" when using an Internet protocol
(e.g. "http://"; or "ftp://";), but for accessing local files the "file:"
or "binfile:" specifier is not treated as a service per se, merely a
keyword to let the engine know to use very different internal routines
than it uses for Internet access.
The POSIX standard that's supposed to govern these things is notoriously
inconsistent among implementations. IIRC the spec calls for any path
that includes more than one "/" to be interpreted as if there is only
one (e.g. "///" becomes "/"). If that was happening here, then using this:
file:///Users/jimhurley/...
...would be the same as:
file:/Users/jimhurley/...
But apparently it isn't.
Perhaps this is a bug in LC. Mark/Monte/Peter: opinions?
Oddly, I believe I've encountered times when "file:///" worked, but not
others (Windows?). Maybe it's dependent on how the host OS handles
paths? FWIW on Ubuntu it works with 1, 2, 3, and even 10 slashes.
In any event, if you change that to use a single slash you should find
that it works:
replace "file:///" with "file:/" in tUrl
put url tUrl into tWhatever
