The "problem" is the accurate model AH has for engine and propeller torque effects.
Simply put, the rotation of your propeller pulls your plane sideways.
To counter this effect - which is most noticable when on the ground - do this:
Pull back your stick 1/4 to 1/2 when you taxi. This locks your tailwheel and keeps your plane straight at low speeds. When you picked up some speed (about 50 mph - this speed depends a bit on the plane) on takeoff, you can slowly relax the stick back to center position so you wont lift off the ground too early. Now use RUDDER (either on JS or A and D keys on keyboard) to keep the plane on the runway.
If you use keyboard for rudder control, youll need to center the rudder again once youre wheels up (S key).
Ailerons are no use when on the ground. They make your plane ROLL (which it cant when wheels down). In the air, when turning you BANK your plane to the side you want to turn to (AILERON) and then PITCH the nose up to make the actualy turn (ELEVATOR).
Here is an article taken from SimHQ on how and when to use RUDDER in the air.
So in a nutshell: On the ground: Rudder, in the air: Aileron/Elevator to "steer" your plane.

Edit: Make sure your stick is calibrated correctly. Also, switch on "Auto Combat Trim" in SETUP > PREFERENCES > FLIGHT - Combat trim will trim your plane for level flight automatically. While youre there, do yourself a favor and turn off the "Stall Limiter" - it will make control of the plane a little more difficult at first, but in the long run, stall limiter REALLY hurts your plane performance and will keep you from winning many a fight.
