As I'm trying to move to OpenOffice.org, I just finished dealing with 2 issues under 3.0 beta 2 worth documenting.
After working with a previous OpenOffice.org version, I was surprised to see that the spell checking was apparently broken after installing the latest beta. The "English spelling and hyphenation dictionaries and thesaurus", version 20051213, appeared under the Extension Manager. Everything appeared in-order under Tools / Options / Language Settings.
Basically, it appears that the current version of the "English spelling and hyphenation dictionaries and thesaurus" extension (version 20051213) is missing files
en_US.aff, which can be downloaded from http://ftp.services.openoffice.org/pub/OpenOffice.org/contrib/dictionaries/en_US.zip (linked to from the Dictionaries page on the OpenOffice.org Wiki.)
Hyperlink Wrapping in Impress
I was pretty impressed with OpenOffice.org's presentation product, Impress. It stands to compete with Microsoft PowerPoint. The one issue I was running into was getting Hyperlinks to wrap lines. I finally found an existing issue logged for this: 43494 - "hyperlinks should support word wrap".
