The column size in Vendors has always been terrible-- why does it default to showing some columns way wider than they need to be, like attachments which is always only a few characters wide, while other longer ones are cut off, why doesn't it remember your column width settings-- but now it has completely stopped working for me. If I go to resize the columns, where I used to get a little two-direction arrow that let me slide the column to the width I wanted, now nothing happens, no arrow appears, and the columns can't be resized.
