Just upgraded and the Tixaxi icon is there in the try when I minimise it but I can't do anything with it - there is no context menu9

Does anything show up when you right click the tray icon? Is the context menu there when you are not minimized? What exactly do you see when you right click the tray icon both when you are minimized and not minimized? If you left click the tray icon while you are minimized does it show the program? What specific Linux are you running?

What distro are you using?

I fixed mine by going to Interface & select Behavior then de select...Use SNI tray icon.

Ubuntu Mate LTS 24.04.4

Tixati v3.44 has be released, try it and see if this is still happening.

so long as i de select...Use SNI tray icon.

Ubuntu Mate LTS 24.04.4

I've upgraded to Tixati 3.44 and the issue still persists. If I downgrade to version 3.42 the tray icon works. If i right click on the tray icon it shows a thin gray bar, left click on the tray icon shows the running program.

What distro are you using? In v3.44 try de-selecting the Use SNI tray icon and see if that works.
