I can't Date Editor in the recent SVN revisions of GRAMPS because when I try to close its window, no matter if I press OK or Cancel, another empty window with same title "Date selection" appears and the program freezes. On Windows python even crashes. Editing date in event reference window works properly.

I also have one question regarding the new database format in GRAMPS. Are the changes made to the database not saved instantly as they were in version 2.2? I've found it a useful feature of 2.2 because my data wasn't lost even if the program crashed.
