OK, maybe the subject line is redundant. The thing is, when I hit "program" and realize I've made a mistake somewhere, I can't cancel it that I can tell. It is similar with hitting "build" as I have lots of files it goes through, and I can't even do anything in MPLAB when it is building or programming. Is there a way to cancel these operations? I am using 5.4 although I know 5.5 is out I think. Thanks! Jeff -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
