> Actually it can be triggered much more often. It is triggered every time editor redraws itself, is that a problem?

OK, I was just wondering if this was normal.

Many thanks for sticky lineWidget commit, it's work on Chorme and Firefox !

> I can't reproduce this...

Oh, sorry. Reverse the problem ! I can go up through a lineWidget, but I can't go down.
And yes, i see this behavior in Chrome and Firefox with last commit.

Another question:
If cursor is at line juste above lineWidget, and I delete this line, lineWidget is deleted too. Is there a way to always let's the lineWidget ?
