I've been working on a few shots lately that are using the Tinderbox HeatHaze 
plugin, and have a question that I hope somebody on here will be able to 
resolve.

Basically, I have a rendered out version of the comp and when I open it and 
toggle between the Write and the render it usually matches exactly. However, if 
I change a frame, refresh, or sometimes just zoom in and out, the output will 
randomly change and no longer match. Sometimes if I keep refreshing it will 
start matching again. I've tried it on checkerboards as well and gotten similar 
results. If I render again, sometimes it comes out matching the original render 
or sometimes it's a completely different result that doesn't match either the 
original or my Write output.

For my own sanity, I'd like to know if this behavior is intentional and if not, 
how do I get it to match up every time. 

Ultimately, it isn't that big of an issue if it doesn't match exactly, I just 
want to understand why it's doing what it's doing. [Question]
