Sometimes, when I use touchpad to control cursor and I'm clicking or double clicking, I move the application window a few pixels because my finger does not tap the touchpad on one place.

Is there a way (Mac OS X) to lock application window, so that it can't be moved with cursor unless unlocked again?

Is there another way to solve this? (Besides me being more careful when double clicking...)

Edit: Is there even an attribute of "window object" that can lock it's position? I can try to write an App that handles just that (or a script run every time I run Application which I want to lock windows for). If there isn't would an OS X Application that "watches" windows movements and counters them (moves back) be hard to code?
