For a few months now, I have had issues with crashing when I do certain things.
Map people
View map when using landmarks
Editing single prims on linked objects
Changing textures on more than about 5 prims at once
Using search in inventory
I have reformatted my pc, gotten a new pc, tried switching out of wireless, defragged pc, updated everything, uninstalled SL a million times, cleared cache...nothing has fixed it.
Since I am a builder, this has made things VERY difficult.
