1) Select some books without series name.
2) Click Set series for all.
3) Paste Old Testament Introduction into the box.
4) Decide that the name is too generic, and that SPCK Old Testament Introduction would be better.
5) Since all that shows in the box is Introduction, start selecting from the right, expecting the text to move so that you can get all the way back to the O.
>> It doesn't happen. To get back to the first letter, you have to click somewhere, and then use the left arrow.
6) Add the SPCK.
7) Remember that you had promised yourself to add a * to the end of custom series, to know that they are custom ones.
8) Experience the same trouble getting back to the last letter.
9) Add the *.
10) Hit Enter.
>> 
- Clear is cut off.
- The series name is invisible.
- The assigned area is far too big.
11) Try to get the series name visible by clicking somewhere.
>> It usually succeeds, but I have also several times ended up with all the books in the series being opened, or the series name being deleted again.
12) The bug in 5) also happens with abbreviated titles, and quite possibly with normal ones (haven't tried). I'm fairly sure it used to work as expected.
13) Don't forget to clear the series name and any altered titles when you're finished experimenting.[:D]
