selection question

[Jim McNeely]

I have a script for a table field like this:

on selectionChanged
	--do lots of stuff
end selectionChanged

This works great, if you click a selection or use the arrow keys it  
runs the script perfectly.

  I also have this slider control, and I'm trying an experiment where  
you do this:

on mouseup
    put the thumbpos of sb "Slider1" into tNum --as per my last email  
and answer!
    select line tNum of field "resultList"
end mouseup

NOW, it hilites the line as if selected, but does not run the on  
SelectionChanged script.

What's up?!!!

TIA,

Jim
