I have LO 5.4.3.2 on Win 10 x64, and Base keeps freezing/hanging on me and I have to kill it with task manager. I’m trying this with some very very simple new databases (both HSQL and FirebirdSQL). I really want to use the embedded FirebirdSQL, but for example after creating two tables and trying to use native SQL to create a foreign key relationship between the tables, Base freezes up when I execute the SQL statement. If I try to create the relationship with the GUI tool, it also freezes.
I haven’t tested HSQL quite as much, but definitely experienced freezes very soon after creating a new HSQL odb document.
