This sounds like PCS is looking for a joystick or paddles. If no paddles
are connected, it will read 255 as position which means "right". The mouse
button is completely separate from the joystick/paddle buttons.
I believe the paddle buttons are located at $c061/c062 while the mouse
button is at $c063 (and though the Tech Ref manual says $c061 would be
the mouse button negated, I didn't find this true on both of my
//c's).

If PCS uses the standard routines for reading the paddles, the PR#4
trick should do it. Otherwise, you'd have to patch the program which
may be difficult, but feasible. I converted the Koala Painter to
use the mouse instead of the Koala Pad some years ago.
