HI, I am using a 18F8710 and developing using MPLAB. I cannot get the Call Stack window and I am trying to understand why - is this a limitation of the tool or it to do with the micro? Any help to clarify this would be appreciated. Thanks! __________________________________________________________ Sent from Yahoo! Mail.
