Seems to be some glitch. It happens to me often when playing alternate. It's not exactly the same.. but I get the same error. More than 40 times i have lost games because of this error. There is a video link in my wall that shows the error. I sent it to WGT, but they don't know what causes this. They told me to right click when it happens and submit the problem... has done it a couple of times. No word on a fix for this. Had another some minutes ago... was winning by 3UP. Bye game.. lost it.
