I bought an HD-LXU3 for the office which has different file transfer system than the HD-LCU3. The HD-LXU3 has [2] prompts for file transfer. The HD-LCU3 has [3] prompts which occur at various times during file copying which is annoying especially when you are copying multiple files-you'll be transferring one when a prompt will pop up from a previous one-Is this a software glitch or something peculiar between the two models?
