Carl, I think the issue you are referring to is on the known issues list:
LD-3544 Maximize on a system with two monitors with different resolution does not fit the screen
I have not seen this issue so Ryan please do report it, and reference this thread. It might raise up the priority of fixing the third party ribbon framework that is causing the issue. The third party vendor has a fix in an updated version but it would cause us to have to refactor a number of items and we want to make sure our efforts are going into what is most beneficial for our customers.
Anyway, sorry for the inconvenience this has caused.
