I took the 2GB card back, expecting a refusal, as companies can be a bit iffy about used electronic components. But the staff were quite happy to swap it for a 4GB, saying that they often get cards returned. and that at times they're the faultiest product they sell. So, grrr for the time wasted but this new card does format and the WAV player does actually work and will soon be annoying museum staff with medleys of 100-year-old vaudeville songs ;-) Thanks for the help and suggestions anyhoo -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
