Perseus SDR freezing up?

[SWVBVA]

Hello All,

Is there anyone out there that owns, or have worked on, a Perseus that knows why they freeze up some times?  Mine will operate for about 5 seconds then freeze.  When I hit the red "X" to close, nothing the first time but my curser doing circles like it is thinking, click it a second time and the window goes opaque with another window of "Not Responding"

Seems to happen if I have had my computer on for a few hours before I turn the radio on.

Any help would be greatly appreciated.

I had this software freezing problem when I was feeding Perseus from a power supply with the negative pole connected to the station ground.

However I noticed that the freezing did not occur when I was using Perseus' own switching power supply.

Then I built a separate 5V - 3A power supply with floating output and the problem disappeared.

It seems freezing is caused by some type of ground loop through the USB connection.

Thank you for the reply!  Not an electronics type.  How does one get a floating output?
