This happens to all of us, and I don't know of any other solutions.
It doesn't happen to me
When it's not in motion, the beer in the line is under the same pressure as the rest of the keg, so there's no reason for it to lose carbonation... unless it's warmer than everything else, or if you're losing carbonation while you pour because your system isn't balanced out.
I suppose CO2 could be permeating out through the wall of the tubing, but I think that's pretty unlikely. If that's the case, try switching to thicker tubing?
