I just installed 4.5.7 on my Windows 7 platform. It works just fine, until DSP audio is turned off. Then I can not turn it back on. ezdac and dac have no effect on the DSP window (i.e. it still says audio is off). ANd when I toggle audio on in the DSP window, the window says ON but there is no audio in the patch. The only way to restart it is to quit and restart MaxMSP. Any ideas?

Thanks,
Dave
