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! -- Dawid Ferenczy http://ferenczy.cz > And the fix is almost perfect.
