Recently I have found icons on my desktop labelled 'hs_err_pid2164' (number varies). When I open this, the document states that 'An unexpected exception has been detected in native ode outside the WM. Unexpected Signal: EXCEPTION_ACCESS_VIOLATION (0x0000050) OCCURRED AT PC=0xAB6243F. Function=Java_Sun_awt_windows_wcolor_getDefaultColor+0x2E1o. After some more like this, there are pages of programming. What is it about? Should I be very worried?
