While searching, there are times when you do not know which is the correct record because lots of similar records shows up after you click 'Find Now'. Then if you open one record then the Open window closes itself. If the record you are looking for is the correct one you have to again click Open Constituent and click 'Previous Search'.
I do not know if that option is already present but it would be really helpful if we have the option either to close or leave the 'Open' Window open.

Thanks!
