Changing logical state of the key not using Send command

I have a code that includes "RButton up::return" for disabling context menu when other hotkeys, RButton & Wheelup/down, is executed and this code seems to keep pressing RButton. Here's my code :

    global RButtonDisable := 0    ;initial variable setting

    RButton::RButton        ;I don't know why but execpt this line, context menu 
                            ;pop up after ~RButton & Wheelup/down hotkeys

    ~RButton & Wheelup::
        Send ^+{Tab}
        RButtonDisable := 1        ;when this value is 1, activate #If
        SetTimer RButtonRecover, -1
    return
    ~RButton & Wheeldown::
        Send ^{Tab}
        RButtonDisable := 1
        SetTimer RButtonRecover, -1
    return

    #If RButtonDisable        ;disabling RButton when hotkeys above are executed
    RButton::return
    RButton up::return        ;this line is needed because context menu pop up
                              ;when RButton is up
    #If

    RButtonRecover:           ;enabling RButton again
        KeyWait RButton
        Sleep 10
        RButtonDisable := 0
        Goto RButton
    return

My goal is disabling context menu only when ~RButton & Wheelup/down hotkeys are executed. This code is working but, I think, because of RButton up::return, my computer recognize RButton is keep pressed which ends up ruin other tasks. So what I want to do is one of two things

1. Changing logical state of RButton from up to down after the ~RButton & Wheelup/down hotkeys, not executing context menu.
2. Disabling RButton with different code approach.

I posted about this question before and found out how to remove context menu : https://www.reddit.com/r/AutoHotkey/comments/14i9fbc/send_esc_right_after_hotkey_routine_is_over/ . But this time I want to make context menu not executed from the start. Can anybody gives some solution?
