[net.micro.atari16] problem with joystick port

Has anyone seen a problem in which a joystick plugged into the
second joystick port on a 520 ST, can confuse the computer into thinking
keys are pressed?

To simulate this, all I have to do is plug the joystick in the port
and start wiggling the joystick in a random fashion.  Sooner or later (usually
sooner) you will hear an audible keyclick.  This causes problems
with games that use the second port as these "fake" keyclicks at
times will pause a game or take it to another mode.

Now, who knows how to fix this?  My computer is of 7/85 vintage.  Maybe
it only affects early computers.

Any information will be appreciated as the local repair people never
heard of this problem.
