Guys, bad news, I have just tried
http://build.koreader.rocks/download...78_2019-08-20/
on both Tolinos, one with FW10.1 (ICS) and 2nd FW 12.2 (KitKat).
1. On ICS, the first startup brought the same bad behaviour - menus and TOC took 4-5 seconds to appear, then I rebooted again, and it looked better ... menus were working fine. But ... I left Tolino on the table untouched, with KoReader showing the book, and suddenly popup appeared informing me in German, that "your Tolino is in the moment busy, please be patient ..."
Then I clicked Windows close button and then KOReader crashed/disappeared ... and this is repeating always as I start it - it shows one page od the book, and after a few seconds it crashes again.
On KitKat, the first startup seemed to be Ok (menus + TOC smoothly), but again the same thing with the popup from Tolino ... after Ok click, KOReader crashed ... This version is some sort of unusable
