How to enable tooltips with vtour Normal droplet

I have made tooltips_buttons="true" in the tour.xml but no tooltips. I read the part about html5 and have tried by using only the flash viewer on a local server and still no tooltips.
1. have html5 tooltips been implemented in the current version 1.19?
2. what may I be doing wrong? NOt showing up using flash or html5
Been looking on board for hours and don't see anything to help.
Thanks

Thanks Klaus, I was beginning to think the answer to my question was so obvious it didn't deserve an answer. I am having a lot of fun with your software. Thanks for all your work!
