I installed the NaN 2.25 Publisher on my Win 98 machine (thanks Ton)
but the GUI has problems. The buttons disappear and the windows won’t draw correctly. The 2.25b version does the same thing.
Are there new drivers for your video card? If so try them.
When I updated to OS X 10.2, the interface looks like it’s melting when I render or click on the Dock. Everything works ok other wise.
