i've tryed it today, no stop detection problems, i could get gps data with internal gps and minigpsd, but when you lanch the program from the icon it launch the server then hangs (but with the server correctly working in the background) before to launch the client. I've just opened another xterm and launch the client there and i got gps-data. Sure the fix is not so fast, you have to be patient..tomorrow i will check if i've misconfigured some option somewhere and if it's possible to have the correct behavior.
with no gps data it works perfectly.
Thanks qwerty12
