In order to access the various categories that you see when you click on “Paintings” in the banner, you have to keep your cursor on “Paintings”, even though there’s a funny icon that comes along with it (not very computer literate!) and spool down to the category you want to see. It will then be highlighted. Click on it, and the paintings in the category will come up.
Sorry about this! Will try to have it behave in a more usual way as soon as I can.
