Hmm, Ok, I've placed the breakpoint in and everything appears to be
fine, but it still doesn't work. This code is essentially a copy/
paste from another area of my app. In that instance its being called
from a ListView contextmenu as well and works fine. What do you mean
exactly by catching ALL the exceptions? Is that something I need to
add into the code?
