I would like to change the color of the dropdown letters (A / B / C ... ) of the matching question. I found this thread: C5.5 Issue with color/colour in matching question drop down list and I tried to change the color via the "Object Style Manager" / Matching Entries but it doesn't affect anything.
The strange part is: If I try to change the color the same way in a new project, it works. I tried deleting the cache, but nothing changes.
