Now when OP clarified that the main and only issue is that editing bumps a question to the top of the queue I have to say two things.
First, I do see some logic in this bumping: once a question was edited it is bumped to draw community's attention to corrections made, so that we can determine the quality of introduced changes, check it for spam, etc.
Secondly, if someone does not like this behaviour, he/she has just switch to the newest questions pagenewest questions page instead of the main page.
