If you *play* two tracks on Deck A and B simultaneously , while dragging one of the waveforms with the mouse, the corresponding player is likely to freeze for a second while producing a strange and awful sound. More precisely, I tried to extremely slow down or stop the the waveform, i.e., like on real turntables when you stop the rotation of the vinyl by using your hands.
This has been tested in Windows 7 X86, Dual Core 2 , 2.66 Ghz, 4 GB RAM, NI Audio 4 DJ with ASIO at 5ms latency.

Please note that these problems do not always occur. On slower systems, however, it seems to be more likely. If you play 4 to 5 songs I'm sure you can reproduce the problem once. Maybe this bug also happens when using time-coded vinyls or jog-wheels.
