As I noted in an earlier post, occasionally some programs will fail and they are terminated. On occasion, however, some programs display very Windows-like behavior, e.g. the only way to use the system is to remove the battery and wait a bit then reboot. Specifically, I'll run a program (fmradio was one such program) and something occurs that prevents me from turning the unit off, closing the application, or doing anything with the system. In short, it's non-functional. I'm concerned that this will, at some point, corrupt the OS. Thus far, whenever this occurs, I uninstall the offending program. Thoughts? Thanks, Nick Shaw
