[Ctk-developers] problem with ctkDICOMViewer on Windows XP

[Marco Nolden]

Maybe just using the series id as directory would be enough? But it also 
looks like it is create the hierarchy twice in the path below, the path 
contains "dicom" and "thumbs". This is probably another bug, I will have 
a look at it.
