External Links

You will need to put the drive letter, or at least the path (if you know the temp drive and the EXE are on the same drive), the reason is this is actually the way Internet Explorer works for directories.  Without this IE only searches the current directory

So Like this
<A HREF="E:\sample\file.htm">Click Here</A>
or
<A HREF="\sample\file.htm">Click Here</A>

In the next version (4) which we expect to ship before the end of January there are a  number nice enhancement on these lines.

We have added the ability to include commands which manipulate the E-Book into links by using the special ## bookmark

For example
<A HREF="##MESSAGEBOX('Hello World')">Display Message</A> displays a message box when clicked
<A HREF="##SEARCH('test')">Click Here</A> - does a search for pages containing test and displays the search results

AND most importantly 3 specific commands

##NAVIGATE - navigate to a particular file in the E-Book
##OPEN - open a page or file into your web browser
##RUN - run a program or command

In all these ## commands you can embed special codes (like the add-ins), for example
{app} is the directory where the E-Book's EXE is located
{appdrive} is the drive where the E-Book's EXE is located
{ebook} is the temp directory
{ebookdrive} is the drive where the the temp directory is

Here are examples of each

<A HREF="##NAVIGATE('{appdrive}:\sample\file.htm')">Navigate</A>

<A HREF="##OPEN('{appdrive}:\sample\file.htm')">Open</A>

<A HREF="##RUN('{appdrive}:\sample\myprogram.exe')">Run A Program</A>

HTH

You're probably itching for the 4 version now  We will try and get it out as soon as possible.  Obviously we want to test it as much as possible before it goes out

In the meantime, if you post a bit more specifics of wat you're trying to do, I'll see if I can suggest a way to solve it on the current version

Oh, and happy new year
