Menu goes crazy on Android device when triggering gesture by mistake

[P5music]

I am testing my CodenameOne app on real android device or emulators.

One of the screens has some controls and a BrowserComponent.

If I touch on the right the menu wants to appear, as the gesture is involved.

And it in fact appears on the right, where it should, 

then it goes to the left,

then it disappears and all is greyed out.

I think it depends on touching that area by mistake

or trying to scroll the BC.

Keeping on touching that area the menu goes crazy as described.

Thanks in advance

It's hard for me to tell from that description. How do you add these menus? What type of menus? Do you have a video?
