When I attempt to Preview a post, the window appears, but is grey background, all the text is center-justified, and the progress bar hangs at about 80% complete.

Maybe a FireBoard CSS file isn't loading completely? The grey background may be from my site template. I'm using the latest Firefox on a Mac.

I suspect some site configuration issue involved, but don't know where to start.

The dialog box says "Read www..com" in the status bar to the left of the progress bar.

BTW, previewing THIS post does the same thing (hang), although it has left justified text and a white background window.

Am trying to upload a screen shot of the hung window...

Have you tried it on any other computers? Mainly; PCs?

I'll have to dig to find a PC. I have five Macs, zero Windows. Getting to one I can use might take a day or so.

First thing, though, is I'll try other Macs and Safari, if the browser is suspect.

did you ever resolve this? i'm have the same problem, with either ie or firefox.

Actually, I'm still seeing this on my G5 using latest Firefox. I must have taught myself to not use the Preview button
