Frustrations

OK. Have the issue narrowed down to the PC. With that said...The same issue happens on my sister's Laptop...So is this really computer related?!

There are several "things" that go on.

One is this black texture that appears:

Two is the disappearing things...like my upper body:

As I can, I'll take screenshots and show everyone as each instance happens. It has to be quick; for, when these mysterious events occur, I crash with no warnings...Just Poof...and gone...Second Life closes.

Please...Any thoughts??????????????
