dont know if this is a "bug". i tried to burn a compilation of folders, when i couldnt i found out there is a separate button for that! ;-)
using the correct button i went browsing for my folder. the only way i could select the folder was to click on it, which opened it. after backing out it would be highlighted and i could add it to the compilation. is this a shortcoming in your program or am i missing something? oh yeah, using win 8.1 with all updates.
ImgBurn works excellently in all other areas and so far i am very happy with your program.
if this continues for another week i will gladly make a donation.
