Forms9i-- Mouse events

Hi Everyone,
We have few forms developed in 9i for a custom accounting package.
and we are having problems with the left hand mouse users.

Few forms uses mouse event triggers and the forms are designed by keeping in mind for right hand users. How to code and change the forms to work for both right and left hand users .. as the right hand users clicks right side button and left users click left button.
Anyone came across with this issues and please post the alternatives to resolves this..
