indeed it seems the keybinder is related to it.
After I disabled the keybinder (be aware of the crashes that sometimes can happen when disabling plug-ins), I closed CB.
Restarted CB --> all icons there. Then I enabled the keybinder again and closed Cb and restarted CB --> keybinder said there was no profile and created a default profile, still all icons there. Closed CB, started CB [no remarks of keybinder this time] --> again 90% icons gone.
[EDIT] : tried this out twice -> reproducable
then a new test [started CB with active keybinder and 90% icons gone], Manage plugins : disable keybinder (hehe no crash ;-) ), checked the menus -> all icons back. Closing CB, and starting CB, all icons remain, but the momnt keybinder is turned on again (see above test procedure) 90% is gone again
