i was editing Prioritization, using advanced prioritization and L4 hung up saying L4 is not responsive. It had been working fine before hand. I waited several minutes to see if it would become responsive again, but no luck. So eventually had to use Task Manager to terminate the program.
L4 ver: 4.2 Beta 1
system: Dell Inspiron 1720, see signature below
Log file: 0676.Logos4 (22).zip There was no current Crash log

Notice that a 2nd taskbar button appeared for Library after the hangup.


Notice the RAM usage was steadily increasing. And one core of the CPU was max'd out.
