Alt+click zooming out the model while I'm using a brush. 3.5r3

I’m asking this because I couldn’t find the answer anywhere else.

So, the problem I’m having is that the alt+click(that zooms in/out the model to fit the screen) is zooming out the model while I’m using a brush, it happens like this, I’m having a close look at the hand of my character so I can carve some depth on it with the standard brush and then I hold alt and then click to carve just a little and then I click again(still holding alt) and the model zooms out even though I’m NOT clicking on the canvas, it happens every time I give the second click.

So, how do I solve this? I thought about simply deleting the “alt+click” hotkey but soon found out it just isn’t possible.
