I have recently purchased a logitech MX400 mouse to replace the Mighty Mouse, whose scroll wheel stopped functioning. I used the LCC to configure the 5 buttons the mouse has, however there is a problem. I want to use my fourth mouse button to serve as a means of interacting with Abracadabra, a mouse gesture plugin for Quicksilver. The problem is that if i use the 4th mouse button in an application, it works perfectly, however, if i use it in the Finder, the button works, and Abracadabra recognises it, but it also creates a lasso to select numerous files, kinda like if i held the left mouse button and dragged. I was wondering if there was a way to prevent the lasso from creating when the 4th mouse button is used in the Finder, as the lasso is extremely annoying and inconvenient.
