I deleted a lot of fonts from my folder because all I could see were rectangles, besides that the folder was full to bursting. With Fantasia and some of my favourite ones, I don't put them in the fonts folder anymore, I have them in a folder in My Docs and just double click on the one I want and then minimise it. It appears in your font drop down menu and you can use it from there.

I have SF de Luxe, have made 1 page since I had it, never used it since x
