I just tried the latest version of duokan 2012 (k3)2012－06－21.C11824.rtm from http://bbs.duokan.com/forum/thread-65239-1-1.html
...... there have been significant improvements in speed and page cropping and smart view features.
But a constant struggle i've faced is with the index....for image based pdfs, it doesn't go the page indicated in the toc....wonder why!!!.....and I need this...esp for books with lots of pages.
Anyways I've reverted to the older Lite2011－12－08.C3283 which i find the most stable.....with no crashes at all......
What do you guys think.....will there ever be a stable version for duokan 2012?.....Please fix this bug.
