Adam,
One the features exposed in V 6.0 is the fast performance, but to change between (Normal / HTML / Preview) take a lot of time because the control always repaint or call the icon image.
In before versions this issue doesn't happened!
The same case is when I move the cursor over the image,
I can see in the IE status bar, a message (download images ...)
It is possible to improve this , or there is an opcion in the control to avoid it???
Thanks for your comments!
