Open Office tweaks

In tools -> Options -> Memory:
Reduce the number of Undo steps to a figure lower than 100. Websites suggest 20 or 30 steps.
Under Graphics cache, set Use for OpenOffice.org to 128 MB (up from the original 6MB).
Set Memory per object to 20MB (up from the default .5MB).
Set the number of objects under Cache for inserted objects at 20.
Check OpenOffice.org Quickstarter.
