I'm not sure if this is a bug, or intentional, but this is the case:
When you use menu events for a custom window, and also add popup items to it, the
rclick event wont trigger, the rest will.
menu @test {
sclick:echo -s sclick in @test!
rclick:echo -s rclick in @test!
; If you disable the following, above will work fine
Popup:echo -s clicked on popup in @test!
}
This bug can be rather anoying in some situations.
