Speaking of unsupported software...
I recently added a new Brother laser printer to my network as the default printer. Whether that had anything to do with it or not, suddenly OpenOffice can't open any of it's old documents. It started out by crashing when asked to print, cycling through it's "recovering document", but then it started crashing as soon as the document was opened. Strangely, this behavior happened on two different machines.
I joined the #openoffice.org channel on Freenode, hoping for some help in troubleshooting this problem, and followed it for a couple of days. Question after question was asked, and I saw very few answers. An actual dialog appears in the channel this morning, but it certainly seems to be a problem in search of a solution.
