Much as using an internet browser bookmark will take you to a completely new page, using IGB bookmarks will clear away data from different species and/or genome versions and replace it with the data contained within the bookmark. The one time that IGB does this differently is if the data sets that are open are from match the same species and genome version in the bookmark; in this case, IGB will just add in any data sets needed or sources not already opened and zoom to the marked location. e.g. Arabidopsis thaliana, genome version June 2009 is selected, and the TAIR9 ALL data set is open. Your bookmark was made for the TAIR9 mRNA data set, same from the matching species and same genome version. When the TAIR9 mRNA bookmark is activated, it will add the TAIR9 mRNA data set, zoom in to the location and then display both the TAIR9 ALL and the TAIR9 mRNA tracks.
