I use Mozilla. On a whim, I tried logging in with Internet Explorer and it worked fine. Back to Mozilla, cleared the cache, restarted, still got the maintenance page.
Wonder if Google was working on making something more Netscape/Mozilla-compatible? Anyway, it seems to be okay now, and next time I'll try a different browser before I whine. :-)
