Hi CC Thanks cc. From my right click context menu I can indeed access Winamp, Helium or Windows Media Player. However, when I am working with PTE I tend already to have loads of imaging and sound software open already (photoshop, fireworks, goldwave etc) and hence the idea that a built-in preview button would not require me to leave the PTE window, or indeed open yet another piece of software. Winamp is my configured player and it has the irritating habit of always switching me to its own screen when I play an mp3 etc... It's just one of those things I can work with 'as is' but in an ideal world..!
