2.0b7 is a beta version and has some known bugs. The one you just reported is already known about. If you want to avoid bugs, please use software version 1.03 which is very stable but has fewer features.

Congratulations on your new toy, and don't forget to read through the FAQ at www.riocar.org.

By the way, if you want to report bugs in the beta, please put them in the "bug reports" forum, thanks.
