Raspberry pi 3 menu handlers not firing on 7" touch screen

Do Xojo menus work on a raspberry pi3 B+ running buster. I made a very simple one that runs well on my Mac. Menu, menu handler with a breakpoint in the fileSave handler.
While remote debugging the RPI3 the menu shows in the 7" touch screen window. You can select the File/Save menu but the handler never fires. Is there something that i could be missing?

The remote debugger menus work fine.

Using Buster 10.1
Xojo 2019 release 3.1

This might have something to do with the difference between touch events and click events. I know that they can’t support every touchscreen hardware out there but I figure if we can get the official one to work that would be nice. <https://xojo.com/issue/55508>

Do they work in other applications (non-xojo)?

Yes they do. Test out any application on the RPI3.

Wrote a Xojo web based lighting control system running on the Chrome browser and that works great.

Alex thanks, looks like its the same problem.

Adding a bit more information which i should have explained earlier
The application notices that the menu has been pressed. When the menu expands and an item is selected the handler does not fire.
