Help with code

[skimask]

I first made a easy program that only made RB1 "blink" and I compiled it and transfered it over..
Then I made the code I just posted and when I compiled it the hex file still has the old easy program.
So the Problem is: if I change the source code and compile it doesnt update the hex file.

So, the old hex file and the new hex file are exactly the same size and have exactly the same contents, just a different date/time stamp?
What does the bottom of the screen say when it's done compiling...if anything?
