The snapshot feature stopped working on Windows. The problem was in MainBase::Save, where the "format" argument was added to "image->save". On Windows the file format must be given in Capitals and in specific formats (e.g. TIFF works, TIF not).

It is much safer to leave the 'format' argument out and let the system guess the format from the file extension.
