Hi chaps, I'm just delving into the Smooth Scrolling addon for the first time...I hate to be picky, picky, picky...but... under the before you start bit in the instructions it says Click on Properties > Site Properties > HTML Format > Tick the checkbox for ‘Write the ID for each object’. ...should that not read >HTML Options ?
Its HTML Options In X8 but HTML Format in X7 and since the help file was written for X7 and everything else remains the same except this little minor discrepancy, I think Neil decided another re-write of the help file wasn't warranted.
