Honestly...
It has not been an issue for me since the time of this report... So either it is fixed, or I haven't needed it again... Or maybe it was something in that project itself and you've run into it?
I'm currently running SPlat on both a win7pro and win8 system and have not seen this happen since x2...
Work around? I must have found one as I moved on with that piece. Maybe it was simply bouncing or freezing the track before doing the export? I honestly don't remember as it was near 2 years ago...
