I am on a less than one year old Macbook, the basic model. I don't know how wide the screen is but it's a laptop screen. Here is what I have tried so far:
1) Tried dragging in between the columns. As I said before, it then turned into arrows, but as soon as I let go of the mouse, it springs back leaving me just as constrained as I was before
2) Tried just making that whole dialogue box bigger. It worked in the moment, but once I closed the edit metadata dialog, it did not remember the settings and next time I went to open it, everything was as before.
I am attaching a screenshot. As you can see, I need more room to see the text fields. I cannot edit books this way. I was just on vacation and have a backlog of 70+ books to add, so I do not relish manually re-adjusting the size of the dialog window every time I add a book. I don't care about seeing anything more than a tony thumbnail cover in this view; I use cover flow when I want to look at covers. I don't need it taking up a third of the screen real estate! I just want back the screen I had before
