I want to have my slider notify me whenever it hits certain values.
I tried setting PANEL_NOTIFY_LEVEL to PANEL_ALL so that I call my 
procedure only when these values get hit. However, it seems that the slider
makes discontinuous jumps in value, (ie it goes from 10 to 15 to 18, say), 
so that values that I am interested in usually get missed.

I tried using an event_handler instead, but I was unable to get the correct
value of the slider using xv_get(slider, PANEL_VALUE). Instead of getting
the value of the slider at the current moment, I get the value of the slider
when I first clicked the mouse.

Can someone help?

Thanks,
Wee-Lee
