Well, they are in the directory structure set up by the install program when it installed MPLAB, so I have no reason to believe this is the case. Also double clicking on the file produces a strange error message, and attempting to open them with Internet Explorer also produces an error. MPLAB produces no error message (would I would expect it to do if the paths were wrong) it just sits there looking dumb. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
