MusicVault Development

Sometimes when dragging to/from a Vault the computer can hang (mostly on Windows Me)
I suspect there is something wrong with the operating system rather than MusicVault, but I am not sure.
Sometimes when dragging to/from a Vault there can be duplicate copies of the files in the Vault.
When using "fast copy" or "fast move" for a long time, the program tends to be slower and slower. I suspect a nasty memory leak somewhere.
VBR is not decoded properly and gives a wrong playtime
