Sometimes, while using vim (no matter, on remote machine or the local one), my arrow keys suddenly stop reacting. I know, a true vimmer should use "hjkl" instead, but the question is different.
I've noticed that if I'm sending application to background, using ^Z, and then calling it back, arrow keys are working again.
Have you noticed such behavior? Can somebody explain from the technical point of view, what is going on behind the scenes?
By the way, even OS's are different, MacOS, debian, FreeBSD.
