- Autoscaling of captured/paused data in the oscope and XY plotter works correctly
- Eliminated a lockup, which could cause audio I/O to halt when a long FFT was being computed.
- FFT and Dual FFT axis labels should be drawn correctly when viewing captured data, particularly when viewing time domain data in the Dual FFT Analyzer.
