Technical Details:
- Platform 12.0b1 (doesn't tested with 11.2)
- PicPick 3.2.0
- This happens intalling PicPick anywhere, the difference is when you execute it form the platform menu (you can also install the platform anywhere, it doesn't depends if you install it on your hard drive or on your external drive).
Run PicPick from its own folder (using its launcher, the exe file), without the platform. Change one specific preference, for example languaje, and then close it (from the tray icon, right click and then on exit) and open it again . All should be normally, and the preference that you change previous should be saved.
Repeat the process launching PicPick from the PortableApps platform. At least for me, the second time you open PicPick the preference that i changed isn't saved.
