In Base, Reports which opened correctly in 4.0.3.3 cause a crash in 4.0.4.2. (Tables, queries and forms operate as expected.) The crash occurs on trying to run the report or edit it. A newly created report (using 'Create Report in Design View') runs, but the program crashes when trying to save the report. I have reverted to 4.0.3 so that I can continue to use reports.
There are many reports about this behavior. It will be fixed in LO 4.0.5 *** This bug has been marked as a duplicate of bug 64279 ***
