Found one more error...
When pressing reset button during rzx playback (in any game), gives me this message: "Opcode overflow during frame xyz, File offset: xxxxxxx"

Still gives "Opcode overflow..." error, when hitting Reset during rzx playback and "Unknown RZX block type" at the end of Olly&Lissa.
In most other cases everything ended correctly with "Finished RZX playback" message.
