Hi, maybe I have found a bug in the Cygwin.
I have been using Cygwin on the 64bit Windows 7 for a long time and I never experienced this problem. But I bought a new laptop and on the fresh new system (also 64bit Windows 7) the same Cygwin with the same configuration cleared the screen buffer whenever I quit LESS, MAN, VIM etc. And it bothered me very much. Because I'm using Cygwin inside ConEmu terminal emulator, I suspected the ConEmu. After a lot of hours comparing everything what potentially could be the cause (environment variables, configurations, software versions etc.), I had a conversation with the ConEmu's author (and he was really great, exemplary support for the free software!). And we finally found the cause. The only difference (or one of few) was in the display size. The old laptop has a screen resolution of 1366 x 768 pixels, while the new one has 1920 x 1080. And I'm using the whole screen for the terminal window. It's really strange, but if the terminal window height is greater than cca 62 lines, the screen buffer is cleared after quitting the LESS, VIM etc. No matters if Cygwin is executed inside the ConEMu or plain cmd.exe. Making the terminal window smaller solved the problem. Window height of 62 lines seems to be fine for me. Also, with some of greater height values, the LESS/VIM process sometimes crashed.
