Primary or Secondary 36?
I have long held the view that Frog is a tool designed for primary students, its implementation is unsuitable for that of a secondary school.
It will be sold on the shiny interface till people realise just how limiting this is, graphic rendering is also appaling.
While I would no longer use slicing to create a page Frog does rather insist on it, however even an round cornered box is unlikey to display correctly due to issues with the system.
