[OpenLayers-Users] markers & popups confusion

[MilesTogoe]

working with examples in 2.6 dev (as of 3/18)

when I look at markers.html there appears to be some automagic in the 
popups calling an alert box but getting the strings in a text file - I 
see the icon url but not the string file url - somewhere it is making 
the connection.  How does one structure the content, especially when 
working from a db array  (via alert box css & text file parsing ?)

when I look at popups.html I see the mousedown events firing the popups 
but don't really see what the difference between the regular and 
anchored popups except that one seems offset from the other and I assume 
that offset in the anchor must be fixed?.    Also this example seems 
pretty buggy - the remove marker layer does not seem to work and when an 
anchored popup is closed, another cannot seem to be opened up (I think 
this is from non-active markers in the same location getting the events ?)

1) which is the more preferable way to add popups (alert box defined in 
the marker or popups with their separate events) ?  or what is really 
the pros/cons of each ?
2) what is the best way to add popup content when adding markers in a 
loop of objects ?
