I've just released the initial beta version of my small helper utility, SmartWheel. The utility allows you to scroll up and down text boxes of background (inactive) windows using the mouse wheel in conjunction with a hotkey (currently CTRL)
It's very simple to use, and requires absolutely no configuration, though there will be a few options coming in the next release.
To use the utility, simply run the executable (it's advisable to add it to the Startup folder to have it running all the time). To scroll any plain text box in any window (active or inactive), simply hold CTRL, put the mouse pointer over the control you want to scroll, and have at it!
More information: (currently unavailable)
Download: See the attached installer, SmartWheel-Setup.exe
The utility currently only works in plain text boxes (eg. boxes without rich text, graphics, smooth scrolling, etc.). I hope to include functionality to scroll any type of field in one of the coming releases.
This is basically my first public software release, so I hope to get some feedback and suggestions from this site.
