I have a problem with the MPLAB help files. The *.chm files appear to have been correctly loaded onto the system during install, but will not open. I cannot understand why as my understanding is that these should open in Internet Explorer (or whatever other favourite browser one has). They will not open from the MPLAB help menu or by attempting to open them directly. MPLAB version 7.50. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
