Logos4Mac has done this for a while.
If you have book selected in the Library Window, then after a while it will jump to the top of the list and select whatever book is at the top. This makes it tough to add MyTags, especially if you're looking at a long list.
When i first open the Library Window, it seems to operate normally, but after a few minutes of playing around it begins to jump to the top again. It will jump every 10-15 seconds or so.
Anyone else experienced this?
