Despite some minor problems in version 4.22, I've stuck to Activ E-Book Compiler over the years and discarded other e-book compilers mainly because of its versatile password protection.Another argument for the Activ E-Book Compiler is Sunil Tanna's reliable feedback and the community services that he offers at his websites.
I always prefer low-level solutions like the simple TXT or HTML formats to file formats that I will not be able to read within a few years.
I very much hope that the next and future versions of Activ E-Book Compiler will remain simple and useful !
I am missing three features (perhaps they have already been integrated in version 5):
(1) readers should be able to turn to the next or previous pages without mouse action simply by striking a key of their keyboard, perhaps SPACE and/or ARROW DOWN for next page and RETURN and/or ARROW UP for previous page; this doesn't work in books compiled with my Compiler v. 4.22.
(2) the ability to chose between a full-page Table of Contents and an editable sidebar. Full-page TOCs will remain useful.
(3) I'm about to change distribution of my e-books from offering a download of a password protected file to the pre-paid selling of the e-book on a CD or DVD. Nevertheless, I need to exclude the unauthorized copying of the file sold. It would be useful to issue or generate a personalized password (computer ID or user's name) for every customer that the customer has to enter after installing the e-book to his hard drive (I'm using a set-up routine). This password would permanently brand the e-book installed so that it cannot be installed on another computer. I don't think that refunding is that much of a problem. It would be helpful to implement such a personalized password protection with as little e-mail communication and internet connectivity as possible.
Like other contributors to this thread, I'd like to know about the script "to access a link after a certain period of time to retrieve the status of the ebook. In case buyers have asked for refund the ebook could automatically turn itself in demo mode."
Best, Hartmut
