[solved) misplaced menu bar

[HEmscher]

Hello!

After some edits inside my top placed menu bar I found, that the application boxes had vanished. After some tryout I found I had to move the Bar with the icons to the right to see this boxes again.
My first layout was from left to right: Menu -applications-system tray.
Now it looks like this: empty space in the size of the Menu bar-applications-Menu-system tray.
I tried to rearrange this in some way but was not able to place the menu bar back to its now empty space.

This occurred after some installations in the building phase of the system and I can not precisely define, when.

Can someone help me, please?
I'll try to help with information if defined.

System: Mate Mint 18.3 64 besides win2k on a 2 kernel AMD on Asrock MB, 4GB 1066-RAM

The prob persists.

So do you have a "normal" panel at the bottom, and a menu bar at the top ?
If so, delete the menu bar, and recreate.
If you only have the one "menu bar" , then add another, and delete the "bad" one.

Thanks. I'll try later. Had a crash and am now rebuilding my system. The ssd with / was not affected by the hardware glitch, (w2k still runs smooth) but the system was unaccesible. Relabeling the partitions with gparted did not mend it, so I decided to install anew. /home was not affected despite being on the nvme, which got loose because the manufacture of the pci-X16-card was so scarce, the thread of the screw broke loose....
By the way: the phenomenon survived the new install. I know, my desktop settings are somewhere in /home, not in /. First I have to restore all the lost applications.

Thanks a lot!

adding a new menu to the desired place and deleting the superfluous one indeed helped!
