Simple question, does Savitar still work, when I update to 10.5.?

Simple answer: yes

Not so much for me. It seems to have an issue with fonts. I did an erase and install (after backing up my world files) and I had Monaco set. After Leopard it's not giving me Monaco. In fact any font I pick off the list does not look like the selected font, or looks like other fonts, or just looks weird, with the text all compressed together. Also if I scroll the window up a little bit and then back down, the text that dissapeared when scrolled comes back looking bold when the rest looks normal.
