I installed on this new Vista x64 box and firefly was running fine but not listing any of the songs that iTunes was finding OK from a mapped drive on my 2003 server. I noticed that as firefly was starting up it failed to register the mapped drives present in Vista. I went out to the “Program Files (x86)firefly media server” folder and opened the mapping.ini file. All the lines in the file were concatenated into one line. I edited the file putting in the proper line endings and saved it. Then started up frefly and all was well.
A curiosity regarding a fresh install on SVN-1696 on Vista Ultimate x64.
