hm,

i'm using glut 3.7.? (don't know exactly which version, but was
included to SuSE 7.3 Linux from fall/2001), and the imps/2 mouse
protocol.

and within the "glutMouseFunc(mouse)" like

void mouse(int button, int state, int x, int y)

the variable "button" is set to

0 (= GLUT_LEFT_BUTTON) if the left button is pressed / released
1 (= GLUT_MIDDLE_BUTTON) if the left button is pressed / released
2 (= GLUT_RIGHT_BUTTON) if the left button is pressed / released

(as you know ;-) and

3 if the wheel turns up
4 if the wheel turn down

regards,

Bjørn

Thank you very much Bjørn for the help.
For me, under windows XP i just noticed that it's not even going into my
'mouse()' function when it's rolled (but it does go in when the middle is
clicked)
I think i'm screwed :)
