I just noticed several events which show as having a reference source; however, when you open the evidence window NO source is shown. There are three sources which no longer show in a listing of all sources.
If you select to implement a source for the data and then select existing and enter find, the sources show in the list and can be set as default and added as the source for the event. HOWEVER, after closing that window (evidence box shows as OK) and then reopening, the evidence window is again BLANK.
I have used Foxpro to open the source library database and can see nothing wrong with the library (the three sources are listed with all pertinent data).
When I look at the project database which links the event number with the source number, a 0 is shown as the Sno and changing it to the correct source number and saving does not correct the problem.
