LOL,

Sorry Darrel, I never saw your post until just now! obviously the time it took me to actually write my last post was when you were writing yours too lol...

I'm going to bench test the code to triple check its doing what it should do, and if not i'll definately give your low level interupt a try.

Thats one thing I never thought about to be honest, as I did try to get the low level interupt working when I first was playing with your includes etc, but I never got it working (the usual, download the files, stick in the project and NOT read the instructions fully! Hmmm.. the phrase 'Look before you leap' springs to mind hehe...)
