Ok, I have a little problem that, as I guess it, is just small mistake on my side.
I'm using calibre to convert comics from cbr to lrf, and it works nice, as long as I just convert a
single file. When I choose several files to convert (that would save me a lot of time

) I don't get the comic convert options in the convert menu at all, and when I click on OK, it does convert the files, but always with the default comic options, which results in images with wrong aspect ratio.
I'm hope I just missed something like a small checkbox in some optionsmenu that would solve my problem immediately
