The Half-assed Input Device has been modified.
Well, not exactly modified, but I did find a way to clear up the wonky mouse-wheel problem.
...by blowing into it like a damn NES cartridge. (Seriously, never do that. It's how you get corroding contacts.) Yeah, it seems that this eight-zillion DPI tournament-ready Elite Gamer Mouse will respond with lightning-fast accuracy and dominate the competition as long as there's no dust. It has allergies.
I'm sure it's improved my reaction time in Adobe InDesign, and I'm crushing nonograms like never before.
