Touch New to Kobo

Hi all,

this is my first post on this forum, since I'm very new to e-reading and Kobo Touch, which I own for more than a month now.

The device is fantastic and I enjoy it everyday and everynight, but there are some "issues" (not sure I can define them as such, therefore the quotation marks) I'd like to share.

First, I bought an epub from a local bookstore (I'm in Italy) and I found impossible to change the default font (Bodoni, I guess: pretty heavy...), probably embedded in the file. I could not even change the size of the font.

Any clue on how to deal with that?

The second thing is that I bought a second epub, again from the same store, this time I had no problems at all with the fonts, but the formatting was not even: some pages showed only 3 lines of text while others were completely empty, in general the paragraphs were not spaced evenly...strangely (or not?), when I uploaded the file to the android tablet I have, all this formatting problems disappeared when opening the file with Aldiko (one of the most downloaded e-reading app for Android) and the book rendered perfectly on the 9" screen of the device, making the reading experience much better than on the Kobo...

How can I get the same reading quality on the Kobo? Is it a reader (e.g. software) limitation?

Does it mean that the rendering engine (if I might call it this way) of Aldiko is better than the Kobo? Or what?

Thanks in advance for all your answers!
