more progress, but a little confusion.

Worked through all the issues of getting everything to work together. Compiled and programmed the blink program that pops up in the MCS program. Mind you I am using MPLAB. Well heres my confusion: with the pauses left at 500, it takes about 5 sec to blink. If I change it to 50, seems about 1/2 sec as the program says it should. Now there are no config,define's, or whatnot, Any thoughts on this?
