Okay, so this

pawn Code:

ShowPlayerDialog(playerid, DIALOG_LOGIN, DIALOG_STYLE_PASSWORD,""COL_WHITE"Login",""COL_RED"You have entered an incorrect password.\n"COL_WHITE"Type your password below to login.","Login","Quit");

Appears after this happens

pawn Code:

stock EnterHouse(playerid, houseid)
{
        SetPlayerPos(playerid, HouseInfo[houseid][InteriorX], HouseInfo[houseid][InteriorY], HouseInfo[houseid][InteriorZ]);
        SetPlayerInterior(playerid, HouseInfo[houseid][Interior]);
        SetPlayerVirtualWorld(playerid, HouseInfo[houseid][VirtualWorld]);
        SetLastHouse(playerid, houseid);
        TogglePlayerControllable(playerid, false);
        GameTextForPlayer(playerid, "~r~Please Wait", 2000, 5);
        SetTimerEx("player_unfreeze", 2000, false, "i", playerid);
        return 1;
}

I think I know what's up,

pawn Code:

case DIALOG_OTHERS_HOUSE:
                {
                        if(!response) return 1;
                        if(HouseInfo[hID][Locked] == 1)
                        {
                                FS_MsgBox(playerid, BOX_STYLE_ERROR, "This house is {FF0000}locked.");
                        }
                        else
                        {
                                EnterHouse(playerid, hID);
                        }
                        return 1;
                }

You did not include list items, so he displays the errorMSGBOX and tp to the location, add the listitem and see if it works. or change

pawn Code:

ShowPlayerDialog(playerid, DIALOG_OTHERS_HOUSE, DIALOG_STYLE_LIST, string, string2, "OK", "Close");

to a MSGBOX
