I suspect the former complaint was a bug that was fixed in the final release of OS2008. At least, I don't have that problem. Does it happen on every site you visit?

Regarding the onscreen keyboard, I know of no way to make it come up when you have a bluetooth keyboard active. You can, however, disconnect the keyboard in order to get it to appear. To do this, click the "B" icon at the top of the screen and click "Disconnect [keyboard model]". Slightly annoying, but it works.
