I too have had the BSOD from LimeWire, I'm not sure what is causing it. There seems to be a conflict between LimeWire, Java JRE 1.5.0_06, and the nVidia Graphics Drivers. At first I thought my Graphics Card was overheating, then I tried deleting the PageFile and then re-adding it to a new location, I have completely removed LimeWire from my system, including folders, registry keys, etc. One way I have found to stop the problem is closing the main window right when it opens, thus moving it to the tray. There may be an excessive amount of VRAM and System RAM allocated at startup. I will have to debug, etc to come to a conclusion, all I know is that 4.10 is the only version this has happen to me.
