I've found that since (at least) using 2.45b I cannot open folders that have a dot in their name (like 'Waiting For You...-King Midas Sound' when I select more than one folder in explorer, right click on the selection and choose "Mp3tag".
All such folders will be reported in a dialog box:
File G:\MP3s\New\Waiting For You...-King Midas Sound cannot be accessed.
I can open the offending folders that way if I only select a single one, though, or I can open all of them if I drag-and-drop them into the now-running Mp3tag instance.
I'm running Windows 7 Ultimate x64 BTW.
np: RJD2 - Games You Can Win (ft. Kenna) (The Colossus)
Yes I can confirm this behaviour on Win XP too, using the new Mp3tagShell ContextMenuHandler.
Error messages e . g.
File X:\MUSIK.SELF.DIVERS cannot be accessed.
File Y:\MUSIK.SELF.MySpace cannot be accessed.
File Z:\MUSIK.SELF.NEU cannot be accessed.
Normal context menu invoking works for File, Directory, Drive, Folder:
"C:\Programme\Mp3tag\Mp3tag.exe" /fp:"%L"
