Developer scroll bar uncontrollable

[edward_glyver]

Hi,

Why do you think my scroll bar (inserted from Developer menu) is acting weird? When I press the arrows, sometimes it moves by incremental change that I've put in, sometimes it moves by a random amount, sometimes it doesn't even stop an go all the way to the end. Even though I press the button only once. What do you think might be causing it?

Thanks,
Edward
