One thing that bothers me about OpenOffice is it seems to take a long time to launch (not as bad Adobe Acrobat). Try these simple tweaks from an article (How to make OpenOffice run faster) I found on the CybertNet Forum. You should see a significant reduction in the start time. A couple notes:
- These directions were written for the Ubuntu version but work just as well with Win XP and Vista (some default settings may differ in Win32 versions).
- Most of us on the forum did not bother enabling the pre-loader but still saw a nice increase in the launch speed.
