[X2Go-User] Menu won't stay up

Greetings,

I am trying to use a cloud VM as my host. The host and guest are Linux.

Host: Ubuntu 22.04 server with mate-desktop and x3goserver installed

Guest: Fedora 35

When the guest connects, I get a desktop. In the upper left corner, I get a Menu. When I click on the menu, a sub-menu gets displayed. However, it disappears before I can select anything.

How can I make the menu work correctly, i.e., stay up until I select something?

Thank you.
