I'm using PropViewer3-beta1.exe & it lacks maximize as well. I'm not seeing it in your freestuff but Rendo is loading slow - maybe the great blizzard.

I'm calling it via the ShellExecuteEx api from my application & it works great but I find that if I call it multiple times without 1st closing it each time, the existing instance is activated but the new prop file isn't loaded. It would be nice if on activation, it could load the new prop. Also, the option to capture the image to the clipboard would be very handy.
