http://ehiti.de/katmouse/i love this little app!!
all it does is it lets you scroll windows even if they are not in focus. you have to have a wheel button though. the NUMBER ONE use i get out of this is while chatting. if i have the chat window open and Firefox open, and i am reading something or going thru google reader i just move the mouse pointer over FF and then i can scroll away while the Chant Window is still on top.
I love this app.
Also helps when i need to compare files in different folders. i dont have to mess with bring something to focus.
i love this app.
