Hello, I don't think I am the only one having issues with this version and the new DSP tab. I have just purchased an asus eepc with XP on it for this job and others, I was kind of expecting the woes of vista and W7 to be overcome I guess, how wrong you can be. Currently no matter that I select for the audio input and output there is still no waterfall display, I recall on one occasion the S/N DB value was changing and some text was seen in the box but no waterfall. If I close the program and run Digipan or APRS messenger it just works, I hope we can get this program to perform like this. I had the waterfall on a W7 machine, I then did as advised for the rxtx putting files in the java directories, since then nothing has been seen of the waterfall, I don't think the two would be related, it just seems to work one day and not the next. I hope we can work this one out, I can see this could be a big step forward for this software. Thanks for any help. Regards Vic
