Hi,
not sure if this is a bug or not... so I report it.
Say I have an mp3 with such tags:
artist: orjan_nilsen_ft_neev_kennedy
title: anywhere_but_here_(radio_edit)
I created an action script to replace "_" with " " for both artist and title
then in the same action script I also added the case conversion to Mixed Case (it is sorted after the replace).
Still the titles are not converted correctly I get such a result:
Anywhere But Here (radio Edit)
Seems that the first character inside the brackets doesn't count as letter to be capitalized. Seems to me you got the single words (separated by space) and the "(" counts as first letter to be capitalized and not the (r.
Well, strange thing is, if I run after my script the standard "Case conversion" available in the Actions after a fresh install of mp3tag, it converts the titles correctly.
I don't think it's a high priority bug, but still I report it 
Thx again for creating this great program, I use it very often and I love it!
Cheers
