suddenly brushes don't work!
Hi all, I'm trying to figure aout what happened with Aperture 3.4.3. Suddenly some brushes stop working. Clone and retouch are ok but skin smoothing, dodge and burn don't produce any effect on the picture.
I looked into the setting with no success, tried a reboot and other things... I don't really understand, I make a large use of skin smoothing and it worked perfectly until yesterday...
Anyone has this same problem?
Thanks in advance for your help!
