Latest Ubuntu update

I'm running Ubuntu 12.04 and after installing all the latest security and recommended updates, I'm having problems with the rtlsdr library relating to rtlsdr_cancel_async. For example: rtl_sdr -f 739000000 -n 1000000 cap.dat The above will successfully capture exactly 1M samples into cap.dat, but it will not exit after the capture is finished. I have to break out with ctrl-c. Anybody having similar problems? Hoping I don't have to re-install Ubuntu... :( James -- *Integrity is a binary state - **either you have it or you don’t.* - John Doerr
