Arrows on polyline

Need arrows on polyline to show direction of travel.

Looked at XMap's reference and did not see arrows on my screen sp I did
not pursue it.

Additionally, javascript console went away when my .js file became
large - is this normal?

I am using ff 1.0.7.

One more item - 1.28 is still leaking in ff 1.0.7.
