Good Morning Klaus,
I am using:
Windows 7- 64 bit- Service Pack 1
Mach 3 Version R3.043.067
Plug In Camera V3.09
Andonstar A1 (2.0 USB) Camera.
All settings are default, as I can not get an unfrozen image to make any changes. No other cameras on the system. Upon starting the plug in, the video immediately freezes. Terminating and restarting the plug in yields the same result. Restarting the Mach 3 software has no effect either. The camera works fine on this computer and my laptop with out going through the Mach3 software. Different USB ports do not make any difference.
