Hello Chuck, I'm trying OPIE2 on PM 28.4.0 even though compatibility is up to v27 on the .
It seems to work fine, however there's a visual glitch on the Configure page:
Also on the same tab, when pressing the "Select extension" button, the pop-up list only lists my A-K extensions and I think the rest (L-Z) are hidden and cannot be selected since there's no scrollbar.
