Thanks for asking. (I'll answer here and delete you identical support
inquiry - please only use one of both for the same question in the
future).
If you globally map "Open Front Row" to Menu (held), that button is no
longer available to Front Row's default settings, which has "Open RB
menu" mapped to that button. RB automatically adjusts your FR mapping
table and moves the "Open RB menu" to a button that doesn't yet have
any action attached to it. Like - for example - the "Plus (held)"
entry. Then, if you hold down the Plus button on your AR to scroll, RB
will no longer directly forward all events to the action mapped under
"Plus", but differentiate between "Plus" and "Plus (held)" and route
the event to the action mapped under "Plus (held)" when you press the
button for some time. A short click will still be routed to the action
under "Plus".
Possible solution:
Go to RB > Prefs > Mapping > Front Row and ensure that "Open
menu" (and no other action, either) is mapped to "Plus (held)" and
manually remove it (by selectin "-" from the dropdown), if there is.
