I have uncovered a bug in openoffice on windows 7, 64 pro Openoffice 4.0.0
To reproduce this bug, make a table with 3 rows and 3 columns (maybe other numbers would work as well) now merge the top row's cells now select a column beneath that merged row, and delete it. that should crash openoffice and lose all your data. workaround? nothing fast. sorry, it's easier to mail your dev than painstakingly drudge your website for the bug database and try to get past whatever prescreening it undoubtedly has. but great free software guys...but please fix that! it's a priorty 1...crash & data loss.
