There is no indication at all of any problem in the Soundtap window - all the messages indicate normal operation. It is only when I look at the file in WavePad that these drop-outs are evident.
I could send you an example file if you want to see the file for yourself. It seems to happen whenever I do a recording. I have cable internet connection, and am using a dual processor PC, so speed shouldn't be an issue. It happens with both mp3 and wav recording.
