While Ubuntu Mate PC was remote access thorough Xrdp from the other computer running under Win10, Xrdp-connection was OK, however, the MATE's "Brisk menu" can be opened once by clicking menu icon at the panel bar but menu window closed immediately. Then no software can be selected in inside of menu items.
This was only happened within "Brisk Menu" icon on Xrdp window.
The other MATE menu items in the panel likes "Advanced MATE menu" , "Classic menu", and "Compact menu " were working properly. Let me know how to fix it by changing any configuration?
