I was researching what resources were considered equivalent to what for another post. I had the Library open to the left, and things usually opened to the right, when I remembered closing them again before opening something else. When I found an Equivalent Resources button I clicked on it to see what it included. During this process I encountered two or three anomalies:
1) W-H, Elzevir, Tischendorf, Newberry, and the SBLGNT first opened without Parallel Resources buttons. When I tried opening them a second time later, the buttons were suddenly there. Except for the SBLGNT, which needed three attempts.
2) The Apostolic Fathers don't seem to have any Parallel Resources buttons no matter how many attempts I do. Shouldn't they have?
3) I had two crashes. I don't know what I did, and I don't have time to research further, but here are the Apple crash logs: 7750.Logos Bible Software 4_2011-05-24-182743_deleted.crash.zip, 2860.Logos Bible Software 4_2011-05-24-190819_deleted.crash.zip
