For me that behavior is "normal" in the sense that I see it happen here all the time, when editing C files, on the average once in a minute. But since it never disrupts my typing I simply got used to it. What's bothering me more is that when I put an overlay somewhere in a buffer and eventually remove it, underlying text properties provided by the font locking mechanism are never restored unless I explicitly edit the line where such properties should be seen. Apparently so, because font locking does not trigger when overlays get removed because that does not count as a buffer change. Another thing I got used to ... martin
