ow, vfat...

ok. I've done a soft symlink via rsh.app from "My pictures" directory to Screens, and it works.
$ ln -s "My pictures" Screens
so the screenshot app saves the screenshots directly in "My pictures", where scribbles works.
I suppose it means I cannot apply a reset, isn't it?
my expertise has come to an end, here
alas, I don't see "take a screenshot" anywhere in button association menus (for it's an italian customization made for IBS, I guess)
