Alright, so I just built a new desktop and have Windows 7 running on it.
I got a Microsoft Wireless Media Desktop 1000 keyboard and mouse combo to use on it. So far it works great - with one issue. When I view an image in Windows Photo Viewer, if I scroll up once, it zooms in by a HUGE amount, somewhere around 600% magnification. It never did this with my old mouse, and this is really annoying as it's completely impractical and I don't ever need to zoom in that far.
Thinking it was IntelliPoint's fault, I uninstalled that, and the problem persists. It works a bit better as a generic HID compliant mouse though... since IntelliPoint removed the scroll settings - so I couldn't tell it how many lines to scroll at once. And it set the value to 11, yeowch!
Does anyone have any experience with super-zooming on the photo viewer and what I might do to fix it?
