• Play second life
• Experience SL just vanishing off your screen

There is no error message and there is no offer to send a crash-report.

It is just over. This can happens on building something (very often if you use the object torus), on attaching something, on receiving or sending an IM and out of a lot of unknown reasons. It happens just if you have minimized your game to do something else. If you look for the icon in the foot-task-list - dissappeared. SL does not run anymore

It is significantly more often with many avatars around and in lag-areas.
And more often at weekends.

On relog you see "the region is just logging you out" - but mostly no offer to send a crash report.
So SL seems not to "know" it has crashed.

PLEASE DO:
Set more
try - except - end
blocks
to find bugs.
Write error messages to be reported to you..

We do know nothing more but "crashed anywhere out of any reason".
And we know, that this item is a showstopper.
Because: this bug occurs very, very, very often.
Today (Saturday) I had it at a certain place about every minute.
After the 7th time you quit whatever you did there.
