Notepad++ Plugin settings disappear

Hi
I'm having problems with the NPPExec settings and other plugin settings in general.
After closing and reopening NP++ they are gone.
I user the latest PA 12.0.5 with latest NP++ (Je suis Charlie edition) installed on my Dropbox

Steps
1. Open NP++ through the platform
2. Press F6 to open the list of saved scripts
3. type a script (something like echo test) and save it (eg with the name test)
4. close NP++
5. Open NP++ through the platform
6. Press F6 again to open the list
7. List is empty again.

I can reproduce this behaviour over and over again.
Does anyone have a solution?

Thanks!
Bart
