I have a wired issue where a tilde sign pops out on the putty window command line when I am logged in remotely to my linux server (RH9). Looks like it gets entered every minute or so, which is very annoying since it messes up what I type on the prompt. What even worse is, that when I edit a file in vi, either this tilde sign or something else interrupts editing session.
My client pc runs windows 7 and it is a first time in years I came across issue like this one.
Any ideas, suggestions, tips greatly appreciated.
