Weird, the save/load works fine for me.
Check in /opt/smartcam_m5/bin
It should remake it with whatevers in the "smartcam:" inputbox everytime you hit "save".

I hadnt tested closing the server on the PC, only closing the program on the N900 (Gstreamer closes if you hit "X", now).

I couldve sworn I had the viewfinder setup to put the logo back up when its unchecked. Ill have to look into it.

I havnt looked at the Linux server for smartcam yet, ill look at it some time.
