A nasty bug that's stopped me from introducing OOo at the office is bug
#53184
It seems the Windows version of OOo can't open files that are on a Windows file server that happens to have a "_" character in it's name. In our case, there's only one such unlucky server in the entire site, but that's the one that our people most commonly use. MS Office users can click on those files with no issue, but nothing happens with OOo. That is, OOo just closes with no warnings, no error messages. The poor program just dies silently.
In http://qa.openoffice.org/issues/show_bug.cgi?id=53184, status says it's "fixed", but the activity log shows it's never been merged into the release version. This is the 3rd release since the bug was declared "fixed", but it's still not released. Scroll to the bottom of that bug report to see the story.
