Query: Great hardware, Poor software

This mouse seems very durable and has good ergonomics. The wheel button has a little too much resistance, but maybe it'll loosen up after a while. The tracking is great. Hardware-wise, this mouse gets 5 stars.The software (called "Office Program Selector") is poor. You can't customize what any of the buttons do. The side buttons are for the back and forward functions in your browser. I would like to be able to assign them to other functions (which you could do with Microsoft mouse devices 5 years ago), but the software won't let me.The middle button opens up a menu that allows you to launch eight programs (Word, Excel, IE, Outlook, etc.) with one click. The problem is, you can't customize the programs that are listed. So, the software gets 1/5 stars, and is now uninstalled on my machine.Hopefully, Iogear will release a new version of their software that fixes these problems. Until then, this mouse gets a thumbs down.
