Re: Max value set for slider is not actual max value in use.

I made pagesize be zero like you suggested and it fixed
problem with max value.  Thank you very much.  With
zero pagesize I can still drag slider, but, I cannot
make it *jump* by clicking to right or left of it anymore.
I lost this feature when I zeroed the page size.

Scrollbars are nice because they have those arrows on the sides.
Scales are nice because values appears above the widget.
Is there a widget that has arrows to sides AND value appearing
above widget so I can fix this bug and get everything I want
all in the same widget??? (Scrollbar + scale = ???)

Thanks,

Chris
