This morning I tried to change the font in a new OO 4-document. That caused a crash of the current beta. Since then OO keeps crashing. Also after complete removal, reboot of my iMac, reinstall of beta. Crash, crash, crash, one after the other. I sent in a host of reports. Now there seems to be no way I can gat back to testing OO 4. I tried current an older beta's, everything crashes. Now what?
