It's nothing important to talk about I think :)

But could I ask you, if you have some spare time (I know that it's stupid 
:) I haven't got any spare time too), could you take a look on preserving 
the whole scrollback buffer, no matters how big it is, please? As I have 
described in my previous post. When I open and exit e.g. the LESS, the 
visible buffer is preserved, but when I scroll up, there is nothing. I have 
scrollback buffer set to the 9999 lines (as it is maximum in the ConEmu).

Thank you very much for your exemplary support!
