No additional plugins in 3514

[MagicMoses]

I installed JOSM 3514 without having a former version on the system (Win7, 64bit).
During installation, the standard plugins were installed correctly and work. When I try to install additional plugins I press F12 to enter the preferences menu. I tick walkingpapers and piclayer (attached screenshot). Both plugins are downloaded and JOSM tells me to restart JOSM in order to use the above mentioned plugins. As I found out, the new plugins are to be seen in the plugin-folder of the installation. After restarting I enter the preferences menu again to look up if the new plugins are still ticked, but the ticks are gone and the plugins still do not work (attached screenshot). I can still find the new plugins in the plugin-folder of the installation. I tried to install several additional plugins in the way discribed above, but the result is always the same.
Let me know, if you need more information.

Hello!

I have exactement the same problem with this version. If installing additional plugins they are gone with the restart.
