With ASIO 2.0 for Waveterminal 192x Selected Sometimes Playback Freezes

This happens once in a while on Windows 7 Ultimate x64. Once it freezes I cannot go into VST Audio Connections to pick anything else. I also notice that playback has static in it right before it freezes. I have to use Task MGR to close Wavelab and restart it. ASIO is not listed anymore in VST Audio Connections but I can pick ASIO4All and it works. In order to get ASIO back in VST Audio Connections I have to restart PC. This has been happening for a long time with 8.0 and 8.5
