Hi Joleen,

I wasn't sure what you meant by "middle mouse probe," so I asked someone over 
on the IDV team what it might be.  They were thinking you might mean the roller 
button, which may control zoom level, but I'm not so sure.  Can you clarify?

I will grab some of the files you've posted and try to figure out what's going 
on.
