I did a clean 3.0.0-Installation on my freshly bought Notebook running Windows Vista 64Bit. Now I can open several of my old files, but some end up in an endless loop (an empty window with "Opening Document" at the bottom is there and there is constant HD activity).
The Sun ODF Plugin for Microsoft Office 2007 is producing the same problem.
One of the documents making trouble is attached. It contains checkboxes. But another file which doesn't contain them and is an ODT (not a ODS like this one) is causing the effect too (can't attach it because it contains our passwords
To work around the problem I installed OpenOffice 2.0 now (the only package < 3 I could find on my computers). I hope that will work until 3.0.1 is out...
