I am not sure if it's a problem but the "saving configuration" utility seems to create a mp3tag.reg that has some problem:
All the strings key are not saved as string but only the 1st charater is saved as it's ASCII code and the rest of the string is lost .
Actual Registy key:
"ConvTTF"="$if($not(%artist%),,%artist% - )$if($not(%album%),,%album% - )$if($not($num(%track%,2)),,$num(%track%,2) - )%title%"
is saved as
"ConvTTF"="36" (36 is ASCII code of '$')
This seems not related to the last V2.32t version.
