I haven't had anything that required a reset, but I have had some problems with text positioning in kepubs with firmware 3.2.0, such as the off-centre text (see pics in
this post.)
There were some (different) problems with the kepub reader in fw 3.1.0 which were quickly fixed in 3.1.1, so I am hoping there will be a quick release of 3.2.1 to fix these issues too. Otherwise I think I will go back to fw 3.1.1 until it gets sorted.
Edit: Or I might just stick to reading epubs for a while. The epub reader is functioning very nicely in 3.2.0, better than the kepub reader.
