Thanks for the backtraces. The changing track height issue should be fixed.

I will have to do some further investigation to figure out why the stop and forget capture issue is occuring. It took me many(0000023:0000020) stop and forget capture passes to reproduce and I got 2 other backtraces meanwhile, so although it may be an issue with the new rewaveview code, the assertion could also just be exposing a deeper issue in other areas.

The issue with stop and forget capture (or at least those relating to the rewaveview branch) should now be fixed.

I repushed the branch to origin/rewaveview, any testing would be appreciated.
