Has anyone experienced MPLAB crashing when programming the demo that comes with FreeRTOS on the Explorer 16 Dev Board but using the ICD2 as a debugger (not programmer)? I basically execute the Debugger/Program option and after that MPLAB is crashing. Here are the details. I would really appreciate if you can suggest what can I be doing wrong.

I have used several different MPLAB versions and it has always been rock solid.  Maybe there is something upsetting in the USB driver?  I would suggest uninstalling the ICD2 drivers, then re-installing them ensuring that you are using the latest version.  If this does not help then perhaps re-installing all the MPLAB tools? Sorry not to be able to offer anything more helpful. Regards.

Richard, thank you for your answer, I agree it was something related to my machine (IBM T60P) and the version of MPLAB (7.60a), once I upgraded to 7.61 the problem went away. Thanks again
