I'm running 2.46a on Linux under wine (never had any problem until now). V 2.45a worked perfectly.
When I try to modify a field in the right panel, mp3tag crashes. I can edit the item, when I press return to finish a window open which says: An unexpected error occured/ Would you like to save a diagnostic file?....
Seems to happen in any field (tried title, album and artist). I get the crash if I press enter or click elsewhere.
