i am an avid reader and fan of caliber software by Kovind.
the recent version, calibre 4.2.0 has an inconvenient bug. when i open a ebook, it does not have margin scrolling provision. earlier versions used to have it.
like in pdf document, when you open a pdf, there is a small scrolling provision so that you can use to scroll through.
please restore it in the next version. otherwise it is very difficult to go to earlier pages/ chapters or scroll at convenience.
hope you will do it.
