Deleting songs from Singer's Database

[Steve Bauer]

I am using 4.06 with XP. I keep a couple of lists for certain singers (in singers database) that contain many songs. I cannot seem to delete songs in the songs database screen. For example in one list under the name "Tena" I have duplicates......I can highlight ia song and hit "delete" and it asks me if I am sure.....I click "Yes" and when the screen is refresed, the duplicate is still there. Is there a way to edit this list easily?

I also can't delete singers "names" and have read from previous post/searches that It may have something to do with a Microsoft Mouse.....?? I keep a lot of these for locals but would like to delete a few.
