i had left my PC running on its battery and went off to do other things. Came back and connected to charger and wokeup the computer (it had gone to sleep or whatever it does, had plenty of battery let btw). After working in the browser for many minutes, i clicked on L4 and started expanding Favorite folders (had several nested) and L4 crashed. L4 did not create a Crash Log (it hasn't done this for a long time). But i did have logging turned on and it is attached here.
L4 ver: 4.0d SR1
