Before build 48, I used to leave MyMoney running for days at a time as I sometimes slowly reconcile and input transactions.
This release seems to randomly crash and/or close after leaving it open for 2-3 days. I do not see any log files, or anything else as to why it is closing. The database and everything seems to be fine (used to some and your wiki directions to check the Derby database).
In addition, on the Mac, I use spaces for multiple desktops. In build 48, select the application no longer causes the spaces to switch to the correct desktop.
Thanks,
Tim
