Hi Daniel,
I am just testing HS V4.1.1 on a J! 2.5 site.
Everything installed correctly.
Set up category etc and a menu link.
When map page loads, the Show Tour tool tips are displayed in the bubble but they seem to appear incorrectly.
Attached are the various bubbles that are displayed. Step 1, 4 and 7 appear to be the only ones that are positioned correctly.
The screenshots were taken with menu closed, if the menu link is set to menu open, then Step 2 is positioned correctly.

I think the problem may come from using absolute positioning, as they are controlled by left and top values, which do not seem to take into account the screen size correctly.
There is some calculations going on, as I can see the left/top values change on resizing browser image.

Just thought I would pass that on.

Simon
