The ability to maintain directional control about the normal axis (Yaw) is the limiting factor for X-wind landings. Although it may be easy enough to keep the aircraft aligned with the runway during the round-out and landing, as the airspeed decreases, rudder effectiveness will reduce and it may be difficult to prevent weathercocking. Therefore, as the X wind component increases, the amount of flap used for landing is normally reduced. This reduces the surface area on which the X wind can act after landing and therefore improves directional control.
Fowler flaps increase your wind area therefore more likely to have that effect of your aircraft. Note I said 'reduced flap setting' not flapless.
It depends of the situation at the time and the aircraft type your flying. Just note the with a nose wheel type aircraft directional control is much easier to maintain on ground than a tail wheel aircraft due to its inherent stability.
Hope this helps!
