--- Comment #17 from LIGHTNING UK! lightning_uk@imgburn.com 2012-05-02 02:56:34 CDT --- Sorry to be a pain but you'd have to retest with ImgBurn 2.5.5.0 or earlier.
All versions after that (i.e. 2.5.6.0 and 2.5.7.0) have a workaround for this problem - as noted in the changelog.
I'm not convinced anything other than a full implementation of 'SHGetKnownFolderIDList' would work properly as the call is basically still failing to return anything useful and 'TVirtualExplorerTree' doesn't check to see if the results are valid before attempting to use them.
