Works fine for me (Win2K, IE 6). The "problem" that I'm seeing is the "list of users browsing" the forum sometimes lists me and other times does NOT list me.... So, there's probably a bug somewhere... This is new software so there'll probably a time of shaking out the roaches!
I am using a Mac with Safari 1.0 as the browser (which is supported by the phpSpell software it says) and it is a no go. It does work using IE as the browser though, so it is something with Safari, not the Mac. No big deal, but it is something to keep in mind.
