I have now made some more testing, still with the same problem...
I updated RR, Flash and Xport to the latest versions available to date, I even tried changing the ports to which Xport creates the virtual ports, same issue.
It really seems like it is Xport which just "lags", which also can be seen on the speedo / gps map when it doesnīt follow correctly. I checked the CPU load aswell, lays around 5% so it canīt be that.
Hasnīt anyone had any problems like this before? Or do you have any ideas how to uninstall every trace of Xport to install it again?
