Have found the Dynamic Album feature to be great value.
Have however found an issue that may be know already but could not find when I searched.
I have dynamic albums called 2010.alb 2011.alb etc in multiple directories locations.
Each has a different in albums= set.
However when you view the library via a browser it starts to get confused and shows the contents of the most recent one viewed for all instances of the particular dynamic album.
I have renamed the .alb files to a unique name but issue continues.
I have changed the display name for the dynamic album and it seems to fix the problem.
So is it not possible to have multiple Dynamic Albums with the same display name e.g. 2011
