Standalone TLB Properties -- setting the Hot spot size ?

Standalone TLB Properties -- setting the Hot spot size ?

1st let me say how much I LOVE & depend upon my TLB!

It's set to Auto-Hide on the R of the screen, Show Delay = 1, Hide Delay = 1,
it's super snappy when I bang against the R desktop w/ the mouse cursor ! & just how I like it.

I was just looking at the Properties dialogue box (the one w/ 0 tabs),
and I think my question might be related to the option called "Hot spot size:",
which is currently set to 0 pixels.

Can I configure it so that TLB will only respond to the mouse activating it,
from only 1/4 of the way up from the bottom -

say if the R side of my screen is 12" tall,
then I'd like the toolbar to pop out only if I would touch it along in the first 3"- 4"
from the bottom of the screen?

then I wouldn't accidently be activating it when I overshoot for the scroll bar in Explorer or browser.

Thanks !!
