Is album art corruption cured in LMS 7.8 ?

Hi

I regularly have to run a full library clear & scan in 7.7.3, to fix missing artwork occurring as a result of routine "new / changed" scans.

Is the bug acknowledged by Logitech ? Are things improved in 7.8 ?

I have a 500GB mp3 library (on USB HD), on Win 7.

Thanks
