Does not see mp3 files?

Am using same version of program on laptop with XP professional and Windows 7 home edition. On XP have no issues whatsoever, but on win 7 program does not see mp3 files in directory? am I missing a setting or what?

Thx in advance

in 7 apparently distinguishes between standard dialogues for file selection and for directory selection.
The latter does not show any files. Just select the directory and MP3tag will load the files in that branch.
