Hi MG, so also just in case it wasn't clear - a reinstall isn't going to clear up any of these things, the UI issue is due to something not working right in IE9 and you can probably clear that up by either uninstalling IE9 and going back to IE8 or possibly just by maximizing the MoI window so that it starts maximized initially.

The fillet problem is also not going to be related to an installation issue - it's just a sensitive tool and there are many things that can prevent successful fillets. It's hard for me to know exactly which thing it is in your particular case there without seeing the file.

But in either case an uninstall/reinstall of MoI isn't going to make any difference.
