This is a cosmetic problem since the DVDDecrypter days so I think I'll just bring it up today.
On non-English Windows OS, certain symbols don't get displayed correctly in the log window of ImgBurn. An example is the "?", as in "DVD?RW", will be displayed as a funny but meaningless character in my CHT language Windows XP: (DVDå´‡W instead of DVD?RW)
Not really a big issue, but as an interface designer, such a minor imperfection can be quite a distraction. So if it can be corrected in the next release, it'd really be great.
