[DUG] graphics stops updating

[Matt Comb]

No thats the same deal. If your main thread reads that property at the same 
time its written then it'll blow.

You can safeguard this with critical sections in the same was as my previous 
example.

As Trevor said, encasing one integer value with a critical section is 
overkill, my example was meant only to show you how you could setup an 
object (or thread) and assign values.
