I already complained about that "feature" !
Any hotspot added induces such a jerk :(
It seems to use a two phases rendering !
1st for the tour and a second for the "click sensitive" area !
In general the area is bigger than the button itself, and is a square angle form.
Using a circle as button will force this unexpected and annoying effect !
Maybe will this bug fixe be our Chritmas present =D, who knows !
PS : This can not be due to a poor client configuration.
My portable PC has a 1GB Graphical card (FX3700), with an SSD system disk of 120GB using a Quad Core from 2.56 GHz and helped with 8GB of RAM !
Based on W7/64 Ultimate brand new installed (a few hours ago).
If this config is not powerful enough for viewing a Tour without these annoying effects I don't know what to buy to get it perfectly working !
