thanks for your help. I did it and it worked fore the example i was given but in the future i'll need to write longer names and i'll have the same problem. It would be possible to make it in two lines when the name reaches X characters?
In next release I'll remove style "white-space:nowrap;" for placemark title.
In this case title will change to 2 or more lines.
I set not break title for set popup size (it comes from my ZhGoogleMap extension). In next release you can also control min width and min height of popup (infowin). And in this case this property is not necessary.
