v2.0.13:
- CHMReader now only shows one entry in the Task List, and when selected should take you to the top most window.

- The context menu for the HTML Viewer has been enabled so that text can be selected and copyed.
- A new option has been added to allow you to control if the temp files should be deleted automatically after a topic is closed. If you do not delete the temp files, it can speed up the loading of other topics as they do not need to be re-extact common files, but it uses more meomory.

- A new version of the WebBrowser wrapper code has been used.
- Loading progress status has been added.

Doesn't work. The latest version, or the previous build all crash.

I agree it takes a while to initially load and parse the book but after that it was sweet. To be fair it was a 17Mb CHM file, so I thought it was acceptable delay for free software. If it hadn't have been for the 'fit to screen' and change text size options, I'd have dumped it. These make it so much easier to read your book. It would be even better if there was a full screen view(no scroll bars or other widgets), like AdobeReader for PPC. All in all, very useful and very helpful, thank you!!

It worked great. It takes sometime to load the book, but works fine after that. It had some issues when reading glossary pages at end of book (maybe hyperlinking got it confused). The rest of the book was fine.
