I'm a new - and rather irritated - owner of brand new 350. It's a great little thing but I'm now at the end of my rope.

Book is from mobileread library - H. Beam Piper omnibus Terro-Human Future History. I didn't try other books. It was transferred to the reader first time with explorer copy/paste and second time with Calibre. Problems are manifesting on both occasions.
Problem 1 - when reading in S size parts of text are missing
but can be seen in M or XS. I found some messages in the forum about this problem, but they are old and offer no help.
My guess - a problem with rendering pages when it comes to this particular size. Anyone familiar with this and can offer any kind of solution?
Problem 2 - some parts of text cannot be selected - to add a note or call a dictionary. This is consistent through all font sizes (or at least XS, S and M I tried).
Have no idea what can cause this. Opened epub in Sigil and looked and the code. Nothing to indicate reason for such behaviour.
