This bug has been known for a while, but I have reported it here because I could not find it in Bugzilla. See the URL for a thread about the problem. Essentially, OpenOffice "seems to" run itself (or parts of itself) at an extremely low priority. When it must share with another process, such as a build or something like SETI@Home, even the simplest operations such as opening a drop menu are slower than a dead slug stuck in frozen molasses. The nice value of OpenOffice and of other processes does not seem to have any effect. Top shows nothing unusual: 17358 siva 15 0 38664 37M 31728 R 0.0 7.5 0:07 soffice.bin This happens both with precompiled and user compiled installations.
i'm not really sure what to say man, OpenOffice is a big big program with about a gagillion components... This is not just on gentoo, it happens on all other systems as well...if you want to submit something to openoffice.orgs issuezilla, go ahead, but i'm going to mark this as invalid becuase i don't think its something i can fix.... if you find a patch, please reopen this bug, or submit a new one under the same name =) I'll be more than happy to apply it
