This has changed for me from 1223 to 1228. In 1228 the autocompletion listbox covers about half of the line I am typing on instead of being below the line. Going back to 1223 reverted to the old behavior.
I've already reverted to 1223 because of this so I can't take a screenshot. But it's not hard to describe. Instead of the VAX list box being below the line I'm typing, the top edge is in middle of the line and covers what I'm typing.
Doesn't change anything. Plus, it works fine with 1223 and this other add-in. It appears that something changed between 1223 and 1228 regarding the location of the list box.
